I'm going to be buying a Z370 mobo for a i7-8700K upgrade from my current X99/i7-5820K system (which is overclocked to 4.5Ghz) .
 
Not sure if this is the right place to ask a bios question but here goes ....

I use a LOT of fans, there are a total of 15  both DC and PWM fans of various sizes (not including the 3 GPU fans).   And, the Coolermaster case style has a lot of venting and airflow.
 
I've always used ASUS motherboards but thinking of switching to a EVGA motherboard because I've been so impressed with the EVGA 1080ti FTW3. 

I don't use any software to control the fans, like Asus Fan Xpert or Speedfan.

Instead, all the fans are controlled using the Asus bios utility fan control feature, which can control both DC and PWM fans.
 
With that bios feature and I can control all the intake and exhaust fans so they only turn on when the case starts to heat up, which doesn't happen that often.   In normal use, many of the intake and exhaust fans are off.    The only fans that are always running are the two CPU cooler fans.    And, with the EVGA FTW3 running so cool even the GPU fans remain off most of the time.
 
But, even when the heat does rise a bit under a heavy load  ...... there are so many fans that if they turn on at all, they still all run at really low rpm and the case always remains very quiet and cool.

The questions are:
 
Is there a similar EVGA Bios Utility feature which should be included in the Z370 mobo Bios ?   Or, would I have to use some type of fan control software to achieve the same result that I get with Asus mobo Bios ?
 
And, if there is a EVGA bios fan control feature ..... can both PWM and DC fans be controlled so they only actually start running at a set temp ?

    i would have two guess but since my 9 year old x58 mobo has that i would say yes.
    wouldn't a 5820 at 4.5 be a side grade ?

    Thanks dgspider !   
     
    I've just never had a EVGA mobo and don't know about the bios options.
     
    The EVGA website/documenation only talks about pwm fans .... I haven't seen anything about DC fans and haven't been able to find any screen shots that show the EVGA bios fan profile options if the fans can stay off until a certain temp is reached.
     
    That's an interesting point about it maybe being just a "side grade" !!
     
     
    I haven't seen any comparable gaming info between a high-overclocked 5820k and the 8700k .....  but I have read that the 5820K is supposed to be great for video editing, server hosting, and more business kind of stuff and not strictly a gaming cpu.
     
    Where the initial reviews of the 8700K is that it is supposed to be a big leap forward for gaming.
     
    I did get lucky with the i7-5820K, it is definitely on the high end of the silicone lottery.
     
    It overclocks easily and runs completely stable at 4.5 Mhz (actually 4582Mhz) with the cooling I've got ..... It passed every CPU stress test no problemo and has never run over 70C even with many hours of high load (witcher 3 on a 2K 34" ultrawide).
     
    But, you're right .....  the 5820K and the 8700K are both 6 core/12 thread CPUs ...... however, they are 3 intel generations apart so I'm "guessing/hoping" that there could be some really good improvement with the newer CPU for gaming, which is the only heavy load that my computer gets.
     
    But, I'm just not certain about that and not certain that spending $600+ for an new mobo and cpu is going to be worth it ...... I could recover maybe 1/2 of that by selling the Asus X99/5820k on ebay, though.
     
    It would be interesting if anybody knows more if there will be much gaming improvement by going to the Z370/8700k from the X99/5820k !!!

    the 5820k in gaming is still very good. I have a 6800k and I have no issues in anything I throw at it, paired with my 1080 FTW2. 
     
    Its easy to compare your cpu with a 8700k, look at game reviews for it, and then run those same games yourself if you can. 
     
    Bottom line though, you WILL get better gaming performance out of the 8700k, but you'll also need to buy a new board and cpu. if that's worth it to you for a few extra frames, by all means.
     
    Here's an example: https://www.youtube.com/watch?v=CZIVaGcax70 6:38 in, crysis benchmark. 
     
    7800X (closest to our CPUs on x299) gets considerably less fps in crysis 3, but it still an extremely high frame rate.

    This might help you make a decision if investing or not.

    http://cpu.userbenchmark.com/Compare/Intel-Core-i7-8700K-vs-Intel-Core-i7-5820K/3937vs2579

    Although, I would wait for more common users to get it and upload more benchmarks.

    I'm jumping from a I7 3820, so I'm expecting to have double performance on the CPU side.

    As for EVGA fans pin on the motherboard. 
    I do know they put PWM pins on their motherboards, but I don't recall ever seeing one MB from EVGA with DC/Pump Control/Hybrid Control header.
    Take a closer look:

    Thanks for the closeup !
     
    Yeah, the fan headers on classified (which is the one I'm interested in) are all 4 pin pwm.
     
    The nice thing about the Asus mobo and Bios is that it even though all their fan headers are also 4 pin pwm, their bios allows you to choose between DC and PWM fans for control.     
     
    And, unfortunately I was only able to buy 70mm fans in DC (and I have a couple of 120mm DC too) so I'd like to have that type of DC fan control with the EVGA mobo bios.
     
    Also, the Asus fan control bios allows to have the fans remain completely off until a specified temp is hit, then they start spinning.
     
    I've heard that some mobo manufacturers don't give that type option and all fans have at least some some voltage going to them at all times ...... and that means the fans will spin at the lowest setting regardless of temp.
     
    .........
     
    Thanks for the link to the 5820/8700 comparison, the problem with all the comparisons I've seen so far is that they all have the 5820 running at 3.3Ghz ...... where the one I have is running at 4.582Ghz.
     
    So, it's hard to know for sure how much improvement I'd get switching.
     
    As method320 pointed out...."look at game reviews for it, and then run those same games yourself if you can."
     
    Which is good advice.
     
    So, I may just sit on the fence for awhile until more game reviews are done with the 8700K overclocked to at least 4.6Ghz which would give a better comparison to what I have currently.

    I would risk myself and say that the PWM/DC pin could be updated via BIOS (would need EVGA to confirm this).
    As far as I know, you can set it up via UEFI Bios on Asus correct? (Don't think that would be necessary a hardware to do this).

    Can't really say about the 0 RPM fan control on EVGA (since I never owned one as well). 
    By this time, on the Z370 platform, I think all major companies will be able to set a configuration for 0 RPM fan mode (come on, companies had plenty of mistakes and corrections by this time to adjust something simple like this).

    evga has always been lacking when comes to fan control, the 370 specs say 6 pwm controlled fans (which is a step back from the 7 headers on the z270 classified which 3 were full pwm, 4 were kinda pwm but followed other fans for their curve ). i hear there is going to be some new software to control them but its not out yet that i know of. i ended up using a corsair link commander pro for my case fans and speedfan to control my three Rad fans via cpu-1 and cpu-2 headers on my z270 classified. asus has been way ahead of every one on the fan side and extras such as pump headers, just wish evga would do the same.
    my other evga board ( x58 classified e-760 ) had one pwm controllable header via speedfan, the rest were all 3 pin headers.

    I would think what EVGA does in the  Z170 and Z270 series in BIOS for fan control would be about the same for Z370.
     
    I have been downloading the PDF manuals as I find them for the different MB's
     
    With the use of USB ports to now control cooling fan and pumps I needed a USB hub  port header expander.
     
    Not ALL the fan headers in the Z170 or Z270 are dual control
     
    My old Antec -1200 has lots of fans with their own control knob but now using the BIG EVGA case

    Thanks !     
     
    Yeah, I was concerned that EVGA bios wouldn't support the PWM and DC fan profiles that I'm used to with ASUS motherboards.
     
    I suspected that they may not control DC fans at all ...... and,that the PWM bios control would only have be with fan profiles that start up at the lowest voltage level immediately.
     
    But, I didn't know for sure.
     
    I just hate using special software (like speedfan) when I'm used to getting the options I like with bios fan control.
     
    Looks like I'm going to have to stick with ASUS if go to a Z370.
     
    But, after reading a bunch of stuff over the past few days I'm leaning towards waiting for the 9th gen Intel CPU, which is supposed to be the Ice Lake.
     
    From what I've been reading, the Ice Lake  will use the 10nm process technology which should be a BIG change in performance from the current 14mn process tech.
     
    It could be like a 40+% jump in performance instead small incremental 3-5% jumps with the evolution of the 14mn CPUs.
     
    Ice Lake is supposed to be released in late 2018/2019 timeframe depending on if intel can get the quality and yield of the 10nm process stabilized.
     
    Hopefully, EVGA will get their bios updated with better fan control by then !!!

    NZXT makes a internal USB hub, works great for expanding headers

    NZXT is the one I have ( should have listed that )
    They make a very good device with almost Apple like pride in even their packaging.
     
    We are almost getting to the point where the MB is the lower price item in a Build
    and the extra help on EVGA ( staff and members ) saves me a lot of time when playing with a new build.

    You might want to send a PM to EVGA TECH staff if you see one.
    Or try directly the support e-mail: support@evga.com
     
    I would try the PM, since they would get a better understanding of the situation. Sometimes the support e-mail can't / forget to answer all questions.

    Speedfan is hands down the best solution for controlling any number and types of fans.
     
    It takes some time to figure out how everything works though, because the UI is a typical engineer design :)

    I downloaded speedfan but it only detects 3 ports on the z370 FTW mobo.  I don't see a profile for it on their site.  Kinda lame this motherboard doesn't have onboard fan control software and I have to jump through hoops to make my fans dynamic.

    I just set mine up in the Bios and if I want to make a change I just go back into the Bios and make the change.
    I really do not want to install more software only to set the MB Fans.

    It's very annoying. I have a Asus Hero IX motherboard in a box next to me that lets you change the fan dynamically to any component's temperature.  I'm really missing that feature right now.  Some of my fans should be able to sit at %0 while the system is idle.  That is not possible with this motherboard.  I'm not sure what I'm going to do here. I'm also having issues with one of my fans not being registered after I drop it below 30%.  I have to load defaults in BIOS and restart for the fan to be recognized again. I just want to make my 1080ti ftw3 hybrid radiator fan quieter.
     
     
    I should be playing BF1 right now. Instead I'm messing around with fan curves in 2018.
     
    **I moved the switch over to BIOS2 and updated and so far my fans are working correctly now. Kinda sucks I can't put the radiator fan on a curve with this motherboard. %60 fan speed seems to be a nice trade off for noise and cooling so far.  We will see.

    I've been setting up my MicroATX Z370 setup and I only have 4 fans (1 is for CPU cooler). Two out front and one up top.
     
    According to the manual, only the 2 CPU fans and the CHA fan have "smart" control for some reason.
     
    Not sure what to do now as far as setup goes. I have the cooler fan on CPU1, the top fan on SYS, and the two front fans on CHA and AUX only due to their placement on the motherboard and clean cable routing.
     
    Should I do something else for wiring the fans? Didn't want to run them all to one motherboard header for fear of doing damage (top is EK vardar 140mm PWM and the 2 fronts are 120mm Gentle Typhoon PWM). CPU fan is a 92mm 3 wire Gentle Typhoon.

    you need to check your fan BUT most fan's I have are only 1/4 amp each  (0.276 Amps )for this Corsair ML140 Pro LED
     
    1 amp is max according to the manual so 2 fans on one with voltage control should be fine.
     
    or if a low speed fan or a 3 speed switch fan just connect to Molex or SATA power cable and leave at one speed

    I wish I read this topic BEFORE buying an EVGA Z370 FTW.   I purchased an EVGA board over ASUS mostly for looks (no rgb/led/plastic crap) and I love their GPU/PSU products.
     
    I have always used ASUS boards with Speedfan.   They have many headers you can control independently both in the bios and with Speedfan.   With this EVGA board I basically have one header CHA_FAN that I can use.    SYS/AUX/PWR fans all have a static % that you can set in the bios which might be useful for someone -- but not me.
     
    So that sucks.  I'm waiting to see what's up with Z390... if I end up swapping out to an 8 core I will definitely pass on another EVGA board.   
     
    As of right now I am looking at the Corsair Commander Pro to do what this motherboard can't... I doubt it works with Speedfan though... and will require Corsair link which also sucks (although better than EVGA's software products).   I haven't found a solution that offers individually controlled PWM headers that I can "add-on" that is compatible with Speedfan :(
     
    The bios is also lacking in a few features (LLC and such) that are very useful for overclocking but that is another story in itself.

    One of the directions EVGA seems to be testing is letting the CASE do the fan controlling.
    This or another third party standalone device seems like a good direction I may explore.
     
    Even the CLC CPU cooler has its own firmware.
     
    The 1 amp limit on the fan header was always a problem for me.
    So on a few builds I just use 3 speed switch fans and direct connect to the 12 volt PS Molex socket.
     
    many time I still see one or more fans in computer systems NOT  moving because of low start up voltage and how many systems have an air flow safety switch.
