FITB Posted March 30, 2013 Share Posted March 30, 2013 So I noticed a my cpu was speed limiting after overclocking and after much research I discovered the reason it was doing this was because my temps were getting to high. So after reseting everything back to stock and running prime95. "Coretemp" is showing that I am in the high 30's at idle and boosts to 91 degrees at full load after about 3 minutes. This is not good at stock or overclocked. I am running the 3930k with the H100 and a 4 fan push pull config exhausting out of the top of my HAF 932 that has more fans than a dog has bones. Airflow is not my problem. It has the stock thermal paste on it. Any thoughts? Thanks. Link to comment Share on other sites More sharing options...
nm3210 Posted March 30, 2013 Share Posted March 30, 2013 It just needs to be re-seated on the CPU. This happens to any cooler. Link to comment Share on other sites More sharing options...
Bryman Posted March 30, 2013 Share Posted March 30, 2013 yup 90C is NOT normal at stock at stock temps should be a MAX of 70-75C...try reseating it Link to comment Share on other sites More sharing options...
ChoPPerNZ Posted March 30, 2013 Share Posted March 30, 2013 Yes try fresh thermal paste as well, i have similar setup with hafx case and 3930k oc 4500mhz and temps are idle 20-30c load 50-60c Link to comment Share on other sites More sharing options...
FITB Posted April 1, 2013 Author Share Posted April 1, 2013 Ok so I picked up some Arctic MX2 and reseated the H100 with the rice grain method. Fired it up and instantly my temps were down around 75c. Great! Right? Wrong. After thinking all was good I tried to OC it again first I tried 4.6 with 1.35V and idle temps were low 50C's under Prime95 load it peaked out at 91 and began throttling. So I lowered everything as low as 4.2 at 1.3V and it was throttling still. Now back at stock, load temps are back up to mid to high 80's. I am beginning to think my H100 is the problem. Note, I didn't mention this first time. I have had this computer setup for almost a year now and was originally running at 4.6 but can't remember the temps, though I do remember it all working. I didn't notice this problem until a couple of weeks ago after a windows 8 upgrade went bad and I had to reinstall windows 7. Then once I had everything reinstalled I was looking at CPUz and noticed the throttling problem. So I don't really no how long it was doing it, I just know when all was new it was all running well. Is there anyway to tell if the H100 is beginning to crap out? Link to comment Share on other sites More sharing options...
Bryman Posted April 1, 2013 Share Posted April 1, 2013 You shouldn't need more than 1.15-1.2 volts for a 4.2ghz clock... Also I think the i7 throttles at 105C... Least the 3770k does and i5s at 100C... Again are you doing blend or small fft because on my computer small fft produces MUCH more heat than blend almost 10C if not more than 10C hotter than blend... But it's a little high but for 1.35 volts not really... Try to keep it below 1.25-1.3 volts might have to do a 4.4ghz clock and 1.225-1.25 volts but that's okay if you don't want high temps...typing on my iPad lol ugh Link to comment Share on other sites More sharing options...
FITB Posted April 1, 2013 Author Share Posted April 1, 2013 Well my comp is throttling it at around 90c according to CoreTemp and CPUz. I was using the Blend Mode on Prime 95. In anycase at Stock speeds it should not be even nearing 90 or 80's. So I don't know. I am not willing to go to a water block but am beginning to think about an air cooler again.

Corsair Employees RAM GUY Posted April 2, 2013 Corsair Employees Share Posted April 2, 2013 If you already have reseated the pump, applied new TIM, and made sure that you have a good contact between the coldplate and CPU and still get these temps, check your pump's rpm, it might be running at low rpm, not enough to dissipate heat from your CPU.

FITB Posted April 2, 2013 Author Share Posted April 2, 2013 Last night I purchased a used H100 and put it on there as a spare because I had my RMA Approved. Sure enough the new pump is working great. It dropped my temps from 85c down to low 60's under Prime95 Full Load at stock. I think that confirms it that my H100 was dieing, I had reseated with Arctice MX-2 twice with no luck. According to my Asus AI Suite II. It was showing 2163RPM which I am assuming was the pump RPM, which appeared normal from my readings. But performance temps were proving the contrary. I am just happy I have something in there now that is working. I have it back overclocked to 4.6 at 1.35V rock solid stable and it's barely touches 79C after running Prime95 for a while and better yet, no throttling anymore. :biggrin: I did notice that when I tipped over my old radiator I could hear the fluid inside gurgle like a bubble was moving around. Is that normal? There shouldn't be any air in there should there? Link to comment Share on other sites More sharing options...
