Fans On case Question

[bellyboy]

hi, im getting really confused with how to position the fans on the back and side of my pc case. no matter which way i do it, my case seems to be full of hot air.......i have on my current case, fittings on the back panel for 2 fans, and one fan on the side, which is a clear side panel, fan in the middle.

Should the fans on the back panel (2 of them, one above the other) be blowing air in, and the fan on the side blowing it out, or vice versa, or, doenst it really matter???? its doing my head in, any help would be greatful, thanks.

side fan blowing air in, both rear fans blowing air out

maybe i need bigger fans, well come to think of it, i need a new athlon64 heatsink, think mine is pants, seems to generate huge amounts of heat, normal temp, for my pc, with athlon64 3000 is 50 degrees. everytime i pull the side case off......microwave time. thanks for that, ill give it a try...and get a better heatsink too!

are they 80mm fans?
and do you have the possibility of a front case fan?

The only other alternative is that your fans are throttled i.e. not running at full speed?

yes, they are 2 - 80mm on the back, and one on the side, no room for one in the front sadly. i think the fans are running at full speed, my cpu fan though, only seems to revolve at 1500.....which seems kind of well....crapola to me, my old cpu fan in my old pc, even that one ran at 2200......think the heatsink and fan need to go...pronto!

on start up i have looked to see if there is a fan speed control, but, i bought a mobo kit when i built this thing (im still finding my way in that department), and i found out my mobo, an asus something, isnt even on the asus website its so crud! must have only cost about 11 quid probably....totally stung with that one, but you live and learn i suppose. thanks for the advice though, much appreciated.

Get a Thermalright XP-120 or SI-120 heatsink and put a good 120mm fan on it. My CPU fan is running at 1000rpm and i have no case fans. The CPU temp at idle is 30c. A lot goes on room temp too.

Or a scythe ninja (scan and tekheads both sell it) and a 120mm slow spin fan... Fairly quiet and very good cooling ability.

I have a skull case with a side fan for the hard drives one on the other side above the graphic card two at the back a 120 front fan a antec blower for the graphic card a the back.
I have a therma take volcano fan and my temp for the cpu is 55 inside the case is 31.
I think i need a new cpu fan.

The heatsink generating lots of heat is a good think - it shows that it's pulling it away from the CPU.

That temp seems fairly high compared to others' A64s (although the little thermometers are notriously inaccurate). A steady pull of air out of the case will help. Intake fans are generally less imortant and usually just add a bit of noise and turbulence.

I was about to post exactly what schmunk posted, the CPU heatsink generating lots of heat is good, as all this heat is coming off the CPU. What you need to sort out is getting your case ambient temperature down, and the closer you get it to room temperature the lower your cpu temp will be. This can be done by simply moving the case away from a radiator.

Aye - turn your heating down, that'll help
