Re: 3090 (Kingpin & others!) - Get that backside VRAM cool! 2021/03/10 09:39:13 (permalink)
I decided to do this properly.



Gonna pull the system, partially drain, swap the block, shorten the tubes that are a little long, then put it back in. Also gives me the chance to work the bubbles out of the top radiator tank.

I might even remove the 45 degree fittings so I can put in the last fan... But that'd be the RAM fan cuz I don't currently have another one to put there XD I have 17 need 18 for that.

Well I do have 3 more black ones that belong to the EK AIO I still haven't resold... Hmmm. Probably swap an X3M on to the radiator and use a black one from the EK AIO for another spot, that way at least they kinda match.

Dude!😂! 
 
Your system pulls already 90 watts by the fans alone🤣.
 
 
I hope, your case is bolted to the table. It might fly away✈️.
 
Do you use fan controllers or let you run them free?

It's all motherboard header controlled via EK fan splitters (power comes from PSU Molex, PWM signal goes to motherboard for fan control) : https://www.ekwb.com/shop/ek-cable-splitter-4-fan-pwm-extended 
 
 
 
I am SUPER happy, the Zalman controller I bought on someone mentioning it in a thread MADE MY CPU BLOCK WORK!!!!!!!!!!!!!!!!!!!!!!!!!!!
 
Put the new block in the loop, got the Zalman RGB controller in while I was working on putting it back together after some leak testing so I figured might as well hook that up, and boom:
 


 
GPU Backplate fan isn't currently in cuz I haven't tested the CPU block for leaks long enough to be comfy fully reassembling the system... and my on board video wouldn't work for some stupid reason to this monitor, on HDMI, so I had to put the video card back in to get video output.
 
But that is one pretty block.
 
I knew it had to be some kind of interface issue, the "Teeth" on the plugs for the Zalman controller seem to be slightly bigger/longer, so they plug well with the CPU block's header.  I just gotta get the Zalman thing's software to control the lighting & we're good to go!

Welp, unfortunately while the lighting now works with the controller - nothing plugged in to said controller responds to said controller's software.
 
But, right now I don't really care about that, because it's working and that makes meh happay.
 
Edit: I suppose what I'll do is put the lighting for the block on the controller, since it works on there, and put everything else back the way it was so I can control it with RGB Fusion.
 
I should probably write EK an update in the RMA thread they got going for my stuff & let them know I got the lighting working... sort of.

Looks good man!
 
So I know I haven't posted many updates after adding thermal pads to the back of my card, along with heatsinks and the fan, but after getting everything put back together, and my system setup in my office (which ambient is much warmer compared to the cool garage) I am super glad I did the mod. My MJTs never exceed 96C, and that's after the backplate mod and that fan running at 80%. I saw the clear improvements, so it makes me wonder how much hotter the MJT would have ran in my office had i not done these mods.

I really wish there were more backplate-side cooling options available.  Doing a block on both sides of the card would be pretty ridiculous for me, tubing wise, and leak testing that would be beyond scary.
 
Currently I plan on getting a HydroCopper block once they're out, and just installing that, leaving the backplate side how I have it now with the pads/plate/paste/heatsinks, since it seems to be working very well.
 
Still looking for decently priced 12W thermal pads for the Die-side of the card when that swap happens, since I'm assuming the HydroCopper block will come with mostly 6W pads.

Thought it'd be funny to point out, my system actually does pull around 90-100W idle, at stock on the CPU, from the wall, so even with the fans in "silent mode" there's quite a bit of power draw going on... and that's also with the CPU pump running at 50% idle.

Asked: Do you think you have enough fans.
 
Me:
 

 
Managed to turn those 45 degree fittings enough to squeeze a fan on the top spot for the radiator's exhaust-side. :-D Looks kinda goofy cuz it's an X3M, but it fits easier than a standard fan too.
Added 2 more Vardars as bottom intake, wired those with the RAM fan & the M.2 fan (below the GPU) to the same EK fan splitter so they're all running at a static ~50%/1500RPM which is silent while moving quite a bit of air.
 
I think other than adding an HDD fan again (which you wouldn't be able to see anyway) later, I'm finally done messing with the fan configuration.
 
I might end up putting 3 X3Ms on the GPU radiator as intake, then swap two of those black fans to the intake-side of the CPU radiator so the CPU radiator has matching fans on the intake side, maybe... the lighting is somehow different on the two bottom fans despite them being oriented the same way, apparently EK's AIO fans have lighting that goes "opposite" what the rest of their fans do O_o dunno why they thought that was a good idea, but I'm not changing it at the moment because doing so would be a lot of work (rewiring, re-affixing the stuff that's rigging those bottom fans to not grind on the bottom area of the case etc).
 
For those keeping score, that is 8+6+5 EK fans in the system now :-P 14 "standard" D-RGB/AIO EK Vardar fans (11 black, 3 white) & 5 EK X3M variety.  So once I put an HDD fan back on, that'll be 20 :-D Maximum airflow yeeeeeeeeet!

I definitely need to do the front side since backside is done already. Once my thermalright pads are in I will be able to post some results.



Please post pad thickness if you can so others know what to use, I'm very interested in doing the face-side of the card just don't want to get in to it until I know what size of pads I need exactly.


I ordered 1.5 mm and 1 mm packs. I need to stack 1.5 and 1 mm for front ram, 1.5 mm x 2 for VRM and 1.5 mm for power phases since putty is gone. For backside I need to stack 1 mm x 2 to make it work.

Right now I have stacked 1.5 mm Arctic pads for all ram at the back w/ default pads that are squished. For front side VRAM I have 1.5 mm stacked against default pads. And also for 1 ram chip I have 1.5 mm stacked against the default pads. Since those are squishy, they press far enough to work just fine. Only my memory junction temps are 100-106 C which is because 3 sides of ram still need to be done. I could’ve done it with the Arctic pad but I am lazy and want to do it w/ thermal right instead due to better heat conductivity, I am also applying MX-4 between pad and copper to increase conductivity. Of course not doing it on ram chips as they can be broken off if paste sticks too hard.

Hope this helps.



Question:
Want to confirm your pad thickness for the front. You claim without squishing the stock default pads...stock default pads removed....you need 2.5mm for the front RAM, 3mm for VRM, and 1.5mm for power phases?

What do you think? (I can't think at all!) What'cha gonna do? (I'm gonna cool my card!) So slide over here, and give me those heat sinks.....your temps are so low...I've got to let you know...I've got to let you know...so slide over here and give me those heat sinks..

If you look at the sizes, only 16 of those are "decent" size, 11 x 11 or 10 x 10.
 
These are the ones I'm using in the majority of areas now: 
https://www.amazon.com/gp/product/B07YWL7DFS/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1
A combination of those & these will cover every area you need to cover:
https://www.amazon.com/gp/product/B07BDKN3XV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
But
You will need either thermal tape or thermal pads (or paste if you want to get messy like I did) to attach the bigger heatsinks - they do not come with anything on them in terms of tape.
Thermal tape I used for some of the big ones over the VRM areas (because they already don't run that hot so using paste woulda been a waste) : https://www.amazon.com/gp/product/B06ZY1JNJV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
You can get the 20mm size or 40mm size (more expensive).  Of course, the 20mm size requires you to put 2 strips per 40mm heatsink, so a bit more tedious, but it's also $13 vs $21 for the roll of tape... and it's not like you'll be using a ton, even if you do the entire backplate area with just tape, you won't go through a noticeable amount of the roll.

I just threw on a 120mm USB fan on top of the backplate where the exposed part of the GPU backplate is located to pull heat out of there. It reduced my TJ Temps by 6*C haha

Just to give you something else to consider (if you have some extra money kicking around lol). We use http://www.coolinnovations.com products at work all the time. Their pin-fin heatsinks are fantastic. You can also have them make you custom parts any size/shape you want (for a fee). They have low-profile ones with built-in fans, or built-in mounting for standard sized fans. then you could screw your fan into it directly instead of having to clip/rig it there somehow. Also, with air blowing directly down into a heat-sink, pin-fin (with round pins) is better than any square/rectangle/slot-fin heatsink you'll find. How much difference will it make in your application? maybe not much. But it could make for a pretty sweet looking setup if you went with their black anodized finish. Something like this or a pair of these would be cool depending on whether you wanted to rig up your own fan header or buy something off the shelf. You could be pretty limited on what would mount an RGB-120mm fan though lol. You'd need something like this and just specify when you quote it with them which height you want based on PN.
 
If you dig around on their website (I can help if you want)...they have some options that are pure copper. These are expensive and they have limited options...but I remember from a different thread how excited you were for pure copper in your build

Like where your going with this!
Lol i hope to at some point here to rais you on your copper sheet with a piece of busbar! Go figure when i didn't have the card i had free time and now that i finally got it i don't even have time to game! O well get it while the getting is good!

So I measured and nothing on the backside is longer then 2mm (Some are close around 1.9 and 1.68) So I bought a bunch of 2mm rubber stoppers. I figure between them and some thermal pads ... should be good) Not everything is in, but I can cut and drill some holes now.

I really wish there were more backplate-side cooling options available.  Doing a block on both sides of the card would be pretty ridiculous for me, tubing wise, and leak testing that would be beyond scary.




 
It's not too bad. You can see it pretty good and feel it with the Fingertip. 

 
 
 
Also, it's not more tubing, if you hook them up in series.

Is that tubing small, or does the picture just make it look small?  It looks very neat, I just think I'd have an aneurism worrying about leaks.

Paste will always out do pads and the only reason it wouldnt is because of poor contact.



Well according to Kryonaut's page, it's transfer rate is 12.6W/mK - so Fuji's 17W pads should perform better, but, I would just want the pads for better transfer from the stuff to the backplate, I'm not taking that paste off the backplate without a really good reason to lol
 
I'll probably get more of the Thermalright 12.8W/mK pads, do the other VRAM chips that don't already have that on them, and leave it at that.


Great work documenting all of this. Invaluable! FYI I fell in to the 17W/mK FujiPoly/Alphacool trap with laptop liquid metal mission. It is dry crumbly needs much higher application pressures than we use in PC and doesn't perform as well as the 14W/mK Alphacool pads. Pop this into google translate unless you speak German of course. https://www.hardwareluxx....eleitpad-test.1093326/
Speaking of which does this look like a scam to anyone? https://www.oquadtree.com...amp;products_id=203433
 
I am about to do the same thing with an FTW3, does anyone know if we are still 2mm and 1.5mm for the back and 1mm for the front?

Nice one Lord, I take it that is the mp5works series back plate cooler. What is the front plate? If you did it again what would you do differently?

That's 13mm OD Tubing (actually it's not Tubing, but Fuel Hose. Build was way more expensive than planned, so I cut cost on the tubing😂)

I would probably take a different Brand Block.
 
This one is a Bykski and it's not too bad, but it comes with the wrong thermal pad and without any  instructions.
 
My plan was to go for aquacomputer or watercool. But both companies still haven't finished development on their FTW3 Blocks

replacing thermal compound on the Graphics  card will nose loose the warranty?

That depends on how the laws in your country are. But evga is one of the best brands to go to, if you want to change thermal compound or coolers.
 
Just make sure, you don't damage anything with your modifications.

Still waiting on parts, I saw someone do this with the memory so it's a thought. Modmymods finally shipped the 900p waterblock so I kinda want to see that in person too.
Waiting on a lot of other parts.

Smol block in on a bic piece of cooper. :-D
 
I have a 10850K & Gigabyte Z490 AORUS Master in my cart and ready to order... not sure I wanna do it though, even though I really want those extra cores etc... and I did the math, after EBay fees reselling the 9900K/Z390 this upgrade would cost me about $300, which is not bad at all... but I can't help thinking if I can get a 5900x or 5950x at MSRP that would be a much nicer upgrade... albeit, more expensive.
If only eVGA made AMD boards I could get one at a discount.

I was thinking about putting 3 of them back there :P each with a fresh run. Be a lot more surface area. Also that block covers more surface area than the hybrid kit.
Or the 900p water block if I can make it fit and not hit Ram. (Though this might be a temp solution till I can avoid hitting the ram. The Alpha cool is 166 x 79 x 15 mm. (6.5 x 3.11 x 0.59 inches)
 
I decided the other day I'm going to get an intel and an AMD. Yesterday I ordered an Optimus waterblock for AM4, and I already own a their waterblock for Intel. I've already spent a chunk of change, it wouldn't hurt to have both. Then I can benchmark my brains out and with the water chiller finally see which one I want as my main gaming PC. One will be my secondary PC.
