I just added some more fans and a fan controller to bump up my Q6600 from 3Ghz to 3.6Ghz :cool:


I'm thinking about moving the 120mm fan in the middle - the one right next to the CPU - up on top of the CPU HSF so it blows on the NB and exhausts at the same time - smart?


Note: the fan above the power supply is blowing cool air at the slot under the CPU fan - the case is compartmentalized.


Q6600 @ 3.6Ghz (400 x 9)
33C idle ~63C under load (max 68C) Can OCCT for 2 hours CPU/RAM Mix and just CPU and just RAM.
34C Motherboard - 56C GPU
 
too many fans can up your temps. Have you tested for such a theory?
 
Whoa with the money spend on those babies you coulda prolly went w/ a cheap H2O setup :p. Lol...

You got so many fans, so many wires, seems like some of the awesome fannage could be getting useless at areas. Clean up the wires and properly mount those bastards, you should get much better airflow.

I've thought about that; I don't really see any "contradictory" fans though.

I think that the 120mm I pointed out that's blowing right on the CPU fan is probably redundant or degrading the performance of the 80MM CPU HSFan. I'm either going to make the 120mm exhaust and point it at the NB... On the other hand, I could have the cpu fan exhaust air and have the 120mm blow air on the CPU HS. Then I could angle the one to the left of it up so it blows on the RAM and NB and, sort-of, exhausts... Thoughts?
 
The case is good. But whats up with the fans beating air?


get the air in, and get it out!

Here is my old beat to death Q6600 on a slight postive pressure set up.

That old Li box runs 24/7 100% load. Get the air in and get it out. Don't beat the crap out of the air beating points.

You are correct. having two fans that close together degrades performance. I've tested it myself.

You really shouldn't be hitting 68c max at only 3.6Ghz.

I was only hitting 62c max with my setup fully loaded. After I did a little bit of extra "lapping/fixing" today, cores 0,1 are hitting around 54-56c full load and cores 2,3 are hitting around 52-54c full load... and it isn't how I would like it yet. The CPU/heatsink contact patch isn't quite centered nor as big as I would like it.

I have some of the equipment for watercooling that's on the sideline: 2x 120x3 rads, 2x liang D5s, tubing, 3x micro res., etc... I just sold one of my 8800GTXs this week ($70 to someone on [H]) and my 2x EK Full Cover 8800GTX blocks because I'm going to build an i7 box with a 285 SSC (to start and then probably SLI) and put that one water. This PC is sort of a temporary solution because when I built it in March it was already obvious that the Nehalem platform was going to be a game changer. I guess you always underestimate the price/power ratio of newer video cards when your "in the moment."

My biggest internal debate is whether or not to get a Silverstone TJ07 so I can put the 2 120x3 rads on the bottom and work out a push/pull or ducted fan solution...
 
-As others have said, seperate the fan thats near the cpu cooler. Use what people call a push&pull cooling, meaning putting that fan on the other side of the cpu cooler helping it cool more.
-Wire management would help. Try cables that are in the path of the airflow, might help a bit.
-The fan at the bottom thats facing up? Im hoping it fell, if not, zip tie it, on the other side of the hd cage to do the same effect as the cpu cooler, push&pull.
-The 2 front fans you have , one near the drive bay then the one next to it, zip tie them together, in a line, then zip tie them from the drive bay under your dvd rom, So theres air flow going towards the cpu cooler and around the gpu/mid area.

Here i did a 7 year old paint airflow patern. Clicky
 
Like this? 36C idle

update: looks like it's topping out around 63C full load, OCCT mix.


 
You are getting the idea, Check the paint pic, the white boxes is where fans would be. Add another fan pushing air to the back out the back of the case that the first cpu fan is moving across the actualy heatsink. Same deal with the bottom part of case near the hd cage. So its the way the cpu cooler is gonna be. Use Zip-ties to put together another fan ontop of the one at the front. So its kinda like how it would be on a 240 rad.

I'm going to do that
 
the fan in the drive bay is useless. its only pushing hot air round.
unmounted fans,, do nothing but push air around it around.

all those fans,, you coulda went water. a simple 120.2 in the front to cool the cpu+nb
a 120.1 in the back to cool the gpu. or a 120.2 on top to cool the gpu.
or a 120.1 in the HDD bay, move that rack back to the second racks position. to cool gpu.

all other fans become exhausts.
 
Just put two powerful 120mm fans on that heatsink if you want low idle/load temps. You've got too many low rpm low cfm fans scattered all over the case when you could've just got the job done with a few Scythe 1900rpm "Slipstreams"s. I've got a two Silverstone FM123 fans in push/pull config on my HDT-S1284EE heatsink and highest load temps in prime 95 so far were 65C according to real temp. Q6600 @ 3.906Mhz, 1.472 load /w LLC enabled in bios.
 
First, you're running your fans in the wrong direction... The only ones that are

Bring cold air in from the back, through the heatsink, then out the side 120mm exhaust.

Blowing out the side seems to work very well. I also backed off of my voltages so my vCore is 1.48 under load.
 
I think he means the bottom part fan near the psu, its bringing in air instead of exhausting. Which he is correct if you do the push&pull fan setup i told you about :cool:

That's facing out now. I'm not seeing temps north of 57C :cool: I also took out a front drive cover so air can move in.

Thank you so much everyone!
 
Oh wow, I must have pressed submit before correcting my sentence.

Bring cold air in from the back of the case, and through the HSF, like I said, so turn both of those fans around, then forget that one you have in the front top portion of the case, that's redundant, the hot air will just flow up there anyway, and like you seem to have done, use the side/door fan as the exhaust, like these cases come with stock, it's the best way.

Also, on the bottom part, bring cold air in the front of the case onto your hard drives, then exhaust that air out the back next to your PSU, the PSU is meant to run with warm air, that's how they're made, they've always been exhaust points for cases, that's why the PSU fan pulls air through itself then out the case.

Actually.. the lower the temp in the PSU the better.... The reason they usually exhaust the hot air it to keep them from saturating the inside of the case with hot air... except on a few Dell models I have seen that throw the hot air from the PS into the case.
 
Take all those fans out (keep 1 intake fan for HDD) and buy a desk fan to blow through your CPU/RAM/GPU.
 
My RAM is only rated for 400Mhz so to save myself the brain damage, I haven't tried it. I have OCZ platinum DDR2-800 and they seem to be picky about timings If you want to experiment and you have suggested v[everything] settings for P7N Diamond: I'll try anything once in the name of science..
 
Nah, He can still improve his cooling, If he wants he can replace his 92nm nocta hsf with a true and it will fit right at home with all that cooling.
 
You have entered the land of diminishing returns. Go H2O.

Going H20 with my i7 build in March.



Wish List

Case: TJ07 (to slam two 120.3s or 1 120.3 and 1 120.2 in the bottom)
Motherboard: Asus WS Evolution (love to get back to ASUS - not an ATI fan)
CPU: Fastest i7 for the $ OC'd when I purchase so I hope there is a second round of desktop i7s coming... +best i7 water block. I see a lot of AquaComputer blocks around, is it marketing or real buzz? Same with the Feaser rads. - are the numbers backing up the popularity?
OS Drive: 1 Intel SSD -Extreme model
GFX: Maybe 1 or 2 EVGA GTX285 SSCs with appropriate water blocks
RAM: Found these on NewEgg and I'm dig'n those timings. Thoughts?
Audio: doing research so I'm probably going to hit http://www.audioadvisor.com/ and "work my way down."​

Ready to toss in

Storage/Norton Ghost Image Holder: 4x WD6400AAKS drives in RAID-1
X-Fi Prelude sound (may replace)
Blu-Ray burner
2x MCP320 rads
2x Liang D5 (Swiftech I think)
2x MCRES reservoirs
1/2" tubing
12 Noctua 120mm fans
1 80mm Noctua (from HSF)
Anything in Sig is fair game...

...except the motherboard and other nonsense.​
 
On air, 3.6 and 68c is perfectly acceptable. The op seriously has too many fans. That is crazy.
 
Haha, I'm idling around 50C at 9x400 on the hotter days...
Don't even ask me what my Prime95 temps are.
