Hey guys. Its been a while since the last time i OC a computer. And i am at it again. I am just having a problem with temps i think. i am using a Corsair H100 cooler.
Specs:
FX8350
Asus M5A99FX Pro 2.0
Ballistic 16gb 1600mhz ram
128gb ssd
Corsair H100 cooler
Ultra Gladiator case
Now at idle i am getting Socket temps of about 33c and core temps of around 17c.
When i use Prime and run Small FFT my core temp stays around 60c and my Socket temp is around 75c.
I think this is a little high.
the H100 didn't fit in the case without some mods. I installed the radiator on top of the case and mounted the fans underneath (in the case) and they are PULLING air from the outside over the radiators.
The other two fans or one intake and one exhaust.
My voltage for the CPU is between 1.25 and 1.2875v
and the cpu/nb is 1.25
I think your fans are currently fighting against a natural convection. I think you may have better luck if you setup the RAD fans to exhaust, and then configure every other fan slot on the case to draw air into the case. Ideally creating a positive pressure environment that assists the flow over the radiator. In doing so you will create an environment where every fan in the system and natural convection is all working towards improving flow over the radiator. Granted this will mean that whatever thermals are dissipated in the case by other components will also be forced through the rad, however, with good FLOW, the air temp entering the radiator will only be very slightly elevated over ambient. The improved flow will more than compensate for the increased charge air temps.

Natural convection is such a tiny force that even the slowest low rpm fans can easily over power it. To quote ehume: air goes where you push it. Personally I'm running top intake on my rad and that gave me better temps over all.
@ djflipnautikz. What RPM setting are you running on the H100? An FX-8350 gets fairly hot when you start to OC so to push high OC's you are going to have to run the fans at the full 2500rpm and even then things might well get to hot before hitting 5.0GHz. Also are you sure thous cuts of yours are big enough and not blocking the radiator?
The holes for the air intake on the radiator need to be at least as big as the fans themselves. I prefer pull configuration to push as far as fan setups as far as radiators go. Air goes where you push it +1 .
Temps are pretty high for your clock and voltage, it's most likely you botched mounting the cooling block or paste application. It makes a huge difference if you can mount the cooling block perfectly flat against the heatspreader on the cpu, it's just too easy to do improperly and not get good contact across the entire heatspreader.
As for the psu, it depends on how many rails it has etc. My 8350 rig will pull 680+ watts when running 5 ghz with 100% load on cpu and gpu. I doubt you will come close to that in daily use though.
About the cpu, paste and the cooling block. I could have fudged it up. I have a question, the h100 cooling block had a grey film on it that was semi sticky, I still added tim, but maybe I shouldn't have and therefore not allowing for efficient transfer?
Well I just purchased three additional fans for my case. I will add one on the side opening, and two additional fans on top of the radiator.
Im going to enlarge the holes, and install some fan grills if its too woobly.
question is how should I setup the fans?
I was thinking to have all the case fans as intake and for the rad, half side Intake and the other half exhaust. Or just exhaust through the rad everything?
The only configuration I have found, that "beats" the traditional intake-low and exhaust-high for CPU temps, was with ALL case fans blowing IN, and the CLC RAD fan exhausting. The "assist" results in as much as a 4C drop in CPU temps for me. This allows me to run 5ghz under load without needing to run the radiator fan at 2400RPM.
The worst cooling performance was with the case operating "backwards" trying to exhaust heat low and pull in fresh up high. Th nuances of convection seem to have an effect, albeit minimal, a couple degrees is still a couple degrees. It could be related to the fact that I run relatively low RPM case fans, so the heat exhausted around the case probably rises right up around the case and gets sucked back in the top, lol.

I did a Small fft on prime and got it down to 52c at socket and 35c at core. Stock voltage of 1.2875.
I have it at 4.4g with stock voltage and it gets max socket 72c and core 53c.
Using prime i think thats ok since its the MOST it will ever i see.
Also i had the stock cpu fan that i kinda had mounted on the rail next to the VRM. and my socket temps was 68c. and my core 51c. Didnt know it would make a difference.
Think i am going to put it back on. i removed it because it was angled, and thought it was doing nothing.
