I've been playing with different fan setups and I believe I got it where the temps are low. Below is a list of my build parts and temps. I was testing this using Prime95 small FFTs and the results below is a 24 hour run (ambient temp = 78F). CPU is at default clock. What are your thoughts on this? Also what would be a good OC goal for everyday use?
CPU: AMD FX-8350 4.0GHz 8-Core Processor CPU Cooler: Corsair H80i 77.0 CFM Liquid CPU Cooler (push pull setup with Corsair SP120) Motherboard: Asus Sabertooth 990FX R2.0 ATX AM3+ Motherboard Memory: G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory Storage: Samsung 840 EVO 120GB 2.5" Solid State Drive Storage: (2) Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive Video Card: MSI Radeon R9 280 3GB TWIN FROZR Video Card Case: Corsair 200R ATX Mid Tower Case Power Supply: Corsair CX 750W 80+ Bronze Certified Semi-Modular ATX Power Supply
Yeah those temps are awesome. "Corsair H80i 77.0 CFM Liquid CPU Cooler" *jealous* I have the same cpu and an 212 Coolermaster Hyper+ or something (air cooled basically). And I'm at:
34*C idle
41*C web browser
52*c minor load (playing games) and
61*C full load (dual rendering or synthetic benchmarks).
I have to lean on making the aio an exhaust. To me the cpu temps are alittle high but not bad . I very much prefer positive air flow. Prime95 is not a good stress test for amd due to the fact it will overvolt more than is needed. Personal note, a Noctua D-14 will get your better temps. Highend Air cooling is pretty good in this day and age and is cheaper that using an aio.
I had the H80i in the rear as exhaust and the temps were high with the ambient temp being 78F. That is what led me to play around with different fan setups. Is aida the only other stress test software I can use? Sorry for the noob questions but this is my first build. This is all new to me. :)
I would switch the top two fans to exhaust, being that's where all the heat in your case will go. Another reason is you have way more intake fans than exhaust. This will pressurize your case but not necessarily create a good flow of fresh air through the case. Your temps are very good for the room temp you have try switching the top two fans to exhaust and see if it helps more. Far as an everyday oc on the 8350 with your current temps you should be good around 4.4 - 4.6ghz. You should be able to get 4.4ghz on stock voltage. I got my 8320 up to 4.2ghz on stock voltage and temps also stayed the same.
What would you recommend for overclocking/stress testing and FX8350? I was using Prime small FFT and custom blend (custom blend is much much cooler), but am using an H100i and I can't get above 1.4 volts without going over 72c on the Socket and 62c on the Core. I'm scared that if the Small FFT temps could happen and I would like to know if that is possible during gaming. I have checked and rechecked the thermal paste and seating. I see so many people hitting 1.5 volts and I assume they are testing their stability. I'm downloading AMD overdrive now just to see what the temps are compared to Prime.
In short I'm stuck at 4.6Ghz at 1.4 volts stable, but almost hitting my thermal limits in small FFT. 4.6 is very reasonable I know, but why can't I get higher in the 1.4 volt areas like it seems so many others can? Any help would be GREATLY appreciated.
