cooling check? and fan speed ok?

post #1 of 7
Thread Starter 
i built myself a new rig a while ago, but never really got to the cooling (i know, i know). today was the first time i started to OC it. at 5% (2301 mhz) OCed, it was stable, but at 7% (2409mhz) my CPU temp hit 70 degrees playing battlefield 2! noticed some green artifacts as well. i rebooted back to stock right away.

it only has the 80mm exhaust fan that came with the case. so today i went out and bought a new 75CFM fan (holy loud!), and tested some setups. these were acquired with Asus Probe.

(these are all at idle, ambient room temp around 75-80 F?)
#1
first i did intake and exhaust fans on the back of the case. (all at stock speed from here on out)
CPU temp: 45 deg cel.
MoBo temp: 44 deg.
GPU temp: 68 deg!
CPU: fan speed: 6308

#2
then i opened the case, and within 8 minutes the temps were down to this:
CPU temp: 35 deg.
MoBo temp: 37 deg.
GPU temp: 58 deg.
CPU: fan speed: 6108

#3
i then left the side off, and placed my household fan 2 feet away:
CPU temp: 32 deg.
MoBo temp: 25 deg.
GPU temp: 51 deg
CPU: fan speed: 4354

#4
i then rearranged the fans to an intake in front, and the more powerful fan as an exhaust in the rear.
CPU temp: 35 deg.
MoBo temp: 29 deg.
GPU temp: 55 deg!
CPU: fan speed: 5921

so, having the household fan on obviously showed the best results, but it's not too feasible for me to do all the time. is there anything else (without to much $$$$$) to get the temps back dow those few degrees? another exhaust fan? better CPU fan? and yes, i rearranged both HDDs above the fan, and moved all the wiring i could out of the way to clean it up.

should i worry about the CPU fan speed being at 6000rmps?

thanks.

the next thing to do would probably be to get a new HSF combo, that should cool you down quite a bit, and give you more room for OCing, and you can get some for not to much money, and its cheap insurance. more case ventilation should help as well, as shown by the fact that your temps went down so much after you took off the side.

Well, you could bring down the ambient temp, thats one reason the temps were so high.

another thing is to get a new HSF or go watercooling, if you get an HSF, id say to get an xp-90c and a good 92mm fan with at least 80cfm.

If you plan on buying a new heatsink for your CPU be sure to buy some artic silver 5. It will lower your temps even more and is way better then whatever thermal paste comes with a newly purchased heatsink, and you can uset his on your GPU too if you want to take the heatsink off to lower its temps some.

thanks, i definitely planned on that. actually, from what i recall, when i bought the cpu/heatsink it didn't come with any thermal paste, nor did i use any. so that could definitely be part of the temp problem...

ah, the room temp is 75-80 F, not Celsius like the other temps. my mixup. unless you figured that out, sorry

yea, 75-80c would be pretty dang hot. in fact it would be almost boiling temp.... (its actually 175f if anyone cares..) and i thought that my room was hot...lol no in all actuality, thats still pretty high ambient, if you could get it down to 70-75 that would help you, well, by about 5 degees f.
