so i got my new case....... took everything out of my old case put it in my new case and broke one of my cdrw's... doh... but to the point... my old case had 1 inlet 90mm fan in the front, 1 inlet 80mm fan in the side, and 1 outlet 80mm fan in the back... (plus psu 2 fans) ... now i have 2 80mm inlet in the front, 1 80mm inlet in the side, 2 exhaust 80mm fans in the back, and 1 exhaust on top 80mm, plus same psu fans...
my ambient temps dont go below 37C... and max load 55-65C.... old setup ambient temp was 16-17C max load 55C.... here is a pic of my new setup.... http://www.emba.uvm.edu/~mjanuszc/overclock/air.jpg red arrows represent air flow... black is for psu exhaust... i have round cables on the way (round floppy, and ide cables) as well as 2x7000rpm 80mm fans for exhaust.... vantec aeroflow for hsf-combo... is there anything i can do with the way i have the fans set up to lower ambient temp? thx

it could be quality of the fans in the case??? Did it come with fans or are you using the same ones from the old case? I just switched one of my cases to a black wavemaster (coolermaster)....and my system is much warmer as well. Then I put some higher cfm coolermaster fans in...still warm. This weekend Im cutting in a window and 120mm for the door and then switching the fans to sunon 50 cfm 80mm's. I think its just in the airflow design of the case. I cant think of anything else for my case anyway.
Same boat as you:-)

it came with 5 fans and i added 2 of my own... except the 90mm one... couldnt fit it anywhere.... but i was messing around with the fan setup and i moved one of the 2 rear exhaust fans to the front, so now i have 3 in the front... temps went down some.. at one point diode temp was down to 22C... but now its around 50C.... speaking of diode temp should i be paying attention to it or the cpu temp... which is much cooler... 37C....

motherboard temp 31C
cpu temp 37C
diode temp 52C

ok i ran burn wizard using sandra... and here are the results http://www.emba.uvm.edu/~mjanuszc/overclock/burn013004.txt

can someone tell me the difference between all the different temp readings?

ie
Board Temperature (i know this one :))
CPU Temperature (know this one too :) )
Power / Aux Temperature <---- ????????? (power supply temp?)
HD / Aux Temperature : <-----------????????? (hard drive temp i would assume?)
PCI / Aux Temperature <--------- ?????????? (pci device temp?)

i ask only because my cpu temp never went over 41 at max load... but power temp went from 22 to 52.... hd temp didnt really change 31 to 33.... also pci temp started at 49C and ended at 51C....

1 fan in the front blowing in and the rest pulling air out is the best config.

i found a contributing factor in mine. I just opened it up to show a buddy and yeah I did change from uv cold cathodes to blue and the blue seem to run alot hotter. The coolermaster l.e.d. fans also changed from uv to blue so Im thinking that maybe blue just isnt the way to go. That really sucks since I just gave all my uv cold cathodes and coolermaster fans to a friend. Funny how being a nice guy can bite you in the a$$ like that....ug:-(

i just put in an order for 2 80mm variable speed fans (7000 rpm max) i'll put both of those in the back.... maybe that'll do the trick....i do have one blue led fan in the front... would 1 led fan make that much difference? and no its not anywahere close to the sensor... behind harddrives.....

dude, i just killed all the lighting and so on. Even with better fans in I was hitting 59c while running 4million pi. I took the door off and ran pi and stopped at 52c. Then I noticed that in my case the psu fans (antec truecontrol 550), and rear case fan are stealing all the air from the cpu fan. When I attenuated the the other 2 fans down in rpm then the cpu fan then I gained a bit more. I guess these wavemasters put the psu too close to the cpu. The other problem is that the o.t.e.s. on the ic7max3 is blocking air from leaving the top off the heatsink. This is the most beautiful mess I've ever built though:-) today Ill cut a 120 in the door and if that doesnt do it the I guess I have to through the h2o back on.

The most desireable air flow and efficient way of cooling is rear exhaust fans situated near the CPU . The case will have been designed so that clean unheated air is pulled through vents on the front, across the MOBO & CPU and out through the rear. One front fan blowing in is all that's required unless you have problems with drives running hot. For more info see

I used this for guidence on my home build
Hope it helps

I thought you need more fan in than out? +ve pressure in the case reduce dust buildup. (or maybe use add your own air filter).

Just position the fans so that you have a wind tunnel effect.
Make sure that you have minimal amount of dangling cables.
Custom made some cardboard tubes to "separate" airflows into/out of the CPU HS.

Good post steve. Getting air out is what we need .Blowing air around and around does`nt help. This becomes warm. The best thing I`ve found so far is the heatsink fan blowing down through the HS. Then fans pulling air out of the case as fast as possible.

true but the 120mm in the window over the cpu dropped me by 10c. The rear fans and psu fans were stealing the air from the cpu fan since the wavemasters are squashed cases:-(. Doesnt help any that my cpu is coooled by an aeroflow while the truecontrol has 2 massive higher cfm fans pulling from it. Opening the lower door during testing helped alot before the 120 so I think i just had too much outgoing and not enough incoming either way. photo http://www.docmodgod.com/mywave.jpg
if your case is just as small and the cpu fan is weaker then the rest then I would think that alot of people may have this problem.

laith --its a raidmax case http://www.newegg.com/app/ViewProductDesc.asp?description=11-1...;depa=1...

i dont think i'll be cutting holes in the case... shouldnt need to.... hopefully by wed/thus i'll get my 2 new fans, 2 round ide cables... (current cables block a lot of the airflow see pic up top) and 1 round floppy cable.... i'll mess around with the setup of the fans to see what makes a difference....

whats weird is that my ide temps fluctualte around 16-20.... which is pretty cool... but as soon as i run anything intensive im up in the mid 50's.... if these fans dont do the trick i'll have to swap out the vantec hsf http://www.newegg.com/app/ViewProductDesc.asp?description=35-1...amp;depa=1 and replace it with something like the thermaltake volcano12... http://www.newegg.com/app/ViewProductDesc.asp?description=35-1...amp;depa=1 anyone have any pro/con opinions about volcano 12?

LMAO...

OK here is what to do..

haveing round ide and flop cable wont make a bit of difference. your wireing is a mess, line the cables together then drop one off on its path to goto what ever. and cabble tie them, at the mo there all over the place and you have turbelence...

the side fan.. make it blow out

im not sure if you can tell from the pic, but my harddrivce ide cables pretty much block any air from the front from getting to the back, thats why the round cables.... i'll try to snap a close up of the hard drive ide cables so that you can get an idea what im talking about... as far as the side fan... all the posts i've read on this forum say to make sure the side fan is blowing air in, not out....

if your cpu fan is blowing towards the heat sink, then blow in.
if your cpu fan is blowing towards your case fan, then blow out.

Compare your intake c/sectional area to exhaust c/sectional area.
Specifically you may want to measure what the real intake area is,
since many cases have a small 3"x1" cutout in the front bottom fascia.

Frequently the intake is the limiting factor on PCs re c/sectional area.


Additionally, if there is a fan port near the CPU, use that to pull the
hot air out of the case - rather than the CPU-cooler recirculating hot air.
The cooler the case is inside, the greater the delta-T between the case
temps (environment for the CPU) and the CPU itself - so better cooling.

Consider the wattages of items in the case, and the cfm needed:
o CPU = 89W (AMD64, just re future u/g)
o Graphics = 55W
o RAM/HD = 40W
o Total = 184W

1500W can be cooled by 300cfm, 184W requires 37cfm.

Now the PSU to supply 184W will draw about 20% more since it is
about 80% efficient at that load, so you need exhaust cfm >45cfm.

So it's not the cfm, but how you use it:
o Check your intake re resistance - you need >45cfm thro it
---- case temps are a good indicator here
o Get hot air away from the CPU-cooler
---- CPU coolers frequently recirculate 40-70% of their own air
---- that reduces delta-T, so reduces efficiency, so increases temps

An exhaust fan close to the CPU is far better than relying on an AMD
approved PSU intake - especially if the PSU is a quiet model since it
will be cooling the CPU less to remain quiet. One fan remove 35cfm
at about 42-45dB(A), but two fans can removed 34cfm at about 19dB(A).

So it comes down to careful design vs throwing cfm (noise) at it.
