I am using an 800D to house the components I have, but I know I may have made a bad choice, since this case is originally meant for water cooling. Too late to change the case now, although it is a great case for cable management, and many other features, I'm starting to believe it sucks for air cooling. The case is full of fans right now, but I think I need better fans. I'm using Scythe Kazes or something like that. Anyways they are LOUD, if you work on servers on a regular basis, you'll understand what I mean by LOUD. Price isnt really an issue here, but I don't want to buy 8 fans and be like ****...
I need (5) 120mm fans and (4) 140mm fans. The specs I am looking for are high static pressure, low dba (25 or less), and red LEDs if possible. And I good controller, my current controller is garbage (NZXT Touch or some crap). I was looking at the Lamptron ones, which look pretty good. Any help would be very much appreciated, I have been going on and on in my head about what fans to buy, but I'm literally stuck, almost about to switch to water cooling, but I would have to buy a ton of stuff.
Whats in the case ?

Thanks for the response. Those noiseblockers are very nice, but $22 per fan.... Was kinda hoping for something a little cheaper. But I may just end up getting these. They seem like they got a lot of good reviews for being very quiet and high cfm, which I need both of. Gotta bite the bullet I guess.

I've been messing with air cooling my 800D for over a year now then I found someone that seemed to have the answer. He suggested that you use a positive air pressure method to cool this case, in his words it's all about intake. So here is what I've done since then, all fans are set as intake fans except the rear fan which is set to exhaust. I removed all of the expansion covers from the unused expansion slots below my graphics card to encourage the air to excape through there. I was very surprised but it works, my processor idles at about 32C and tops out around 44C (and this is with an old Zalman 9700 CPU Cooler). As for my graphics card it Idles around 43C and tops at about 65C I think I can get the graphics card a bit lower by replacing the stock fan on the bottom of the case with one that moves more air which should lower the air temp in the lower part of the case, ambient temps in my room run about 78F. Also remember that the Fan that cools the Hard Drives does NOTHING for the case cooling, the air it moves exits behind the Motherboard Tray. When I mounted the top 3 fans to intake air they made alot of noise due to air turbulance as the air was pulled through the mesh on top of the case. I found an answer to this as well, I gutted 3 old plain black 120MM fans and turned them into spacers. I then attached the actual fans to them and then attached the whole thing to the top of the case where the fans attach, I used case fan screws for both. All this does is move the fans down a bit to stop the air turbulance and get rid of the noise the fans still move the same amount of air as they always have, but once the case side is on the case is remarkably quiet.  Found this too in my research but don't want to use it because it would destroy that wonderful side panel window which is one of the reasons I wanted the case to begin with. But if it can help anyone else that's awesome too. 800D Side Fan.structionsg

You really do get what you pay for. NoiseBlocker units (the higher speed ones anyway) are some of the only fans thats perform as well in real life as they say they do on the box. If you do more research into most other fans you will see that either the CFM or noise level (or both) specs are exaggerated. Plus the 7 year warranty that the NB units come with is a win. BTW, I have the highest speed/CFM units and I can't hear them over anything else in my case. HAL: Instead of cutting a hole in your side window, you can always use a few of your front 5.25" bays to install more intake fan(s). http://www.frozencpu.com/...ANMODULE_BZ-502B_.html

I wasn't planning on cutting a hole in my side panel just found in my research that some people had and found the schematic on how to do it as well and just wanted to share it in case it could help someone! I used a positive air pressure cooling system and mine is cooling just fine for my need with on extra fans or mods. But thanks for looking out for my side panel window.

Noiseblockers are not worth the price as they cost about the same as Scythe GentleTyphoons which have similar or better noise/airflow ratio, and better static pressure. It's hard to match the build quality of GentleTyphoons as well. Following that diagram up there is a good idea, although I'm against Aerocool fans. I think the 800D only has 140mm fan mounts on the bottom, right? If so, go for some Silverstone AP141s. http://www.newegg.com/Product/Product.aspx?Item=N82E16835220046&Tpk=ap141 I don't know what size fan mounts exist on the back of the 800D, if it's 140mm only than another AP141 is the best choice. If it supports 120mm fans then you can go for a GentleTyphoon or even a Yate Loon. Cutting a hole in the side panel for some 120mm intake fans is a great idea.

Good luck finding GTs in stock in the US @ a price under what the NB units sell for. IIRC, the new AP-15s have also had QC issues with their bushings but thats just scuttlebutt from the [H] forums.
Also, the stock fans in the 800D are 140mm.

for the people who want to usae a positive system and dont like the look of open expansion slots . Silverstone sells there grilled slots. link: http://www.silverstonetek.com/product.php?pid=170&area=en i know they come stock on most silverstone cases. i own a raven and these work wonders and letting the air escape while aslo looking good.

Techmasterjoe, this is someone on the forums you should get in touch with he can make you a custom fan controller that you can get to run and / or power all of your fans. In addition to making your fans smart if you want some fans to move faster then others at all times. In addition to changing speeds even just from ambient temps. Not just case temps.

If you have positive air pressure, you don't need expansions slot covers at all. Just remove them all together. edit: sorry I didn't see Hypn0t1q79's post above. However we are talking about the back of my case. Something no one ever sees unless I'm working on the rig. I think Id rather just remove my stock slot covers for free. Just IMO. boredgunner
For higher airflow 140mm fans go for these.

Those are the exact same units I upgraded my stock 140mm fans to. Awesome products and I can't hear them over my GTX-480s at idle fan speeds.

I think i have an answer or a solution for you Maverick, I also own an 800D case but its water cooled, i had a 360rad in it with fans Noctua brand, and spent a bundle on these fans, and as per my ears, there is no other fan on the market that is quiter per RPM, Sp. and cfm ratings. But as my wife would say, my ears are too damn sensitive. the case was overheating big time. I was blowing air into the case to keep a positive pressure, to keep the dust out. 3 top 120's blowing inward, 140mm below blowing inward..... HD fan 149mm blowing out and i had an H50 with a koolance 120x38MM blowing outwards through the H50 Rad. still no go...I noticed that when i crack the said panel open a bit the temp would drop about 20-30F within minutes. The case just sux when it comes to air cooling. I bought another side panel from Microcenter for 29.00..... and bought this from frozencpu... http://www.frozencpu.com/...Mesh_Panels-Page1.html . I removed the plexiglass on the side panel, unscrew the small nuts... measure and cut the screen, and mount it on to the side panel where the plexiglass was. You'll have plenty of cooling now and no headaches from the fans. I used this panel in summertime and the new plexiglass one in winter time. Video cards will have cool air supply to them also.... only draw back you won't see into the case as well in the summer months. So , i hope this idea helps...good luck oooops almost forgot....before you turn on the pc...run to home depot and pickup window air conditioner foam filter and cut it to the size of the new opening, unless you like dust.

IIRC your major mistake was making your rear 140mm fan an intake unit. You would probably have realized much better temps with it exhausting hot air out of the case (as in the hot air coming directly off of your radiator).
I have my rear 140mm fan as an exhaust and my H100 as an intake at the top of the 800D. I can feel quite a bit of hot air being expelled out the back. I can only imagine all of that hot air getting blown back into the case if the rear fan was acting as an intake.

That's really odd that you tried a positive air pressure cooling solution and it didn't work?? I'm running my 800D with the 3 top fans set to intake, the bottom fan to intake and the back fan on exhaust. I have 1 EVGA GTX 285 SSC edition and a Phenom II X4 965 BE cooled be the original Zalman 9700 cooler. My temps run CPU: about 32-35C idle and about 40-45C normal game load around 52C when all 4 cores are loaded, like when encoding video. as for my GPU: it idles around 40C and the hottest I've seen it go when gaming was 61C which is way below the upper threshold from my graphics card. Now I live in Arizona average temp outside in the day is 105 - 110 F, the usual temp in the room my computer is in is about 78F. If I turn the room AC on I can get my temps to go down to like 30C idle 35C loaded on my CPU and 35C idle and 46 - 48 standard load on GPU. All in all never had a problem since I went to the positive pressure system before that when trying different fan combos I always ended up pulling the side panel off was the only way to cool it. Oh yeah one other thing I only found the Positive system works if you give the air somewhere to go I pulled the expansion slot covers below my Graphics card to encourage the air to head there to help keep the air under the Graphics fan cooler. Will eventually get around to ordering some vented covers but for now I'm just happy to have the case cooling with the side panel on and not sitting in the closet. Just got some new fans today to replace the stock 140MM bottom and back fan and they didn't really help the CPU temps much but did help the GPU temps lowered them by about 5C across the board. The fans I replaced the stock one with are the AreoCool Sharks, put a plain black one in the bottom and the Blue LED one on the back. They move a crap load more air the the stock Corsair fans did so that mean the air at the bottom is probably cooler so the GPU is cooler in turn.

Just because you run positive case air pressure does not mean that you will get good temps. Really the main benefit to having positive air pressure to to aid in the cooling of internal components while keeping dust to a minimum. That being said, if the air pressure in your case is comprised of warm/hot air, your components are going to suffer. This is why it is very important to make sure that you have proper exhaust in your case as well.
Basically, you don't need a buttload of positive air pressure for this to work. Ideally what you would want is a bit more air coming in versus going out. That way you will have the positive air pressure you require while making sure that no hot/stale air is building up inside the case, which in turn heats up your components.
As I said, make your rear 140mm fan an exhaust unit (and upgrade it to a higher CFM fan if you have a stock Corsair unit still) and you will most likely realize a large drop on CPU temps (and probably your other components as well).

My rear fan is set to Exhaust always has been, oh and I've tried every fan combo you can think of with this case and this is the only one that has worked period! Every other one and everything would just slowly heat up and not cool back down till I removed the side panel. Oh and if you don't have dust filters on the fans no matter what you do even with positive pressure you'll get dust inside the case!

i'm very intersted on how this is done how did u mount the fans to the shrouds? exactly what kinda screws did u use? is all this work really worth it for lower noise?

I used a pair of side cutter pliers to cut the structure that holds the fan motor at the center from the main body of the fan so that all that was left was the square part with the circle area where the fan blades used to spin. then at the spots where I had cut I used a file to grind down the rough edge left my the cutting. Once this was done to my satisfaction, and I tend to be a perfectionist, I simply used the same type of fan screws that you typically get with a fan that you use to attach the fans to the case to screw the gutted fan to the complete fan. Then just attached the whole thing to the top of the case with the same type of screws as the other step. As for weather it is worth it to do this or not, all I can say is it was worth it to me. When I installed the fans directly to the top of the case I thought I'd just fired up a jet engine. After making the spacers all I hear is a slight hum and a bit of a his from the air as it gets sucked in. But I can't hear it at all when I'm playing a game or watching a movie, it doesn't even bug me when I'm sleeping as I sometimes run it all night if I'm downloading a large file of some kind. I'll pull one of them out here soon and take some pictures and try to post them to give you a better idea of what I did. in the mean time here are some pics I pulled from the net and modified to help show what I did hope this has helps some but let me know if not and I'll try to do better LoL.

Talk about luck - I am rebuilding my system - Considering the Corsair cases and the Lian-Li cases. The positive airflow factor is exactly what I am looking for. No glory on a WC system yet! It will take some time for that to come around. The advice in this thread has been fabolous, thank you.
