J_abellana Posted April 27, 2013 Share Posted April 27, 2013 Hi, I've just mounted the H60, ( 2 fans at push pull config pulling air out of the case with two 120 case fans blowing air directly on top of the CPU and the GPU plus one 120 in the front panel) the cpu is at stock speed & voltage at idle,the i7-3770's four coretemps average at 28c-34c (ambient at around 26c) but during prime, the cores average 75c-79c (@3.9Ghz boost clock) I've looked around using google-foo and most people average 10c lower. Do I have bad contact or is this totally normal? Link to comment Share on other sites More sharing options...
wytnyt Posted April 27, 2013 Share Posted April 27, 2013 systems do vary and your temps arent all that bad,if an after market tim was used it may need cure time to get max temp range. Link to comment Share on other sites More sharing options...
J_abellana Posted April 28, 2013 Author Share Posted April 28, 2013 I did use deepcool's cheaper lower end thermal paste though (z3 I think) . You think getting one of the more expensive ones would make a difference? As it is a non-k proc, I'm never going to overclock it. but I live in the tropics and it can get quite toasty. I'd love to have some headroom since I'd be running it at full load for some 3d rendering. Link to comment Share on other sites More sharing options...
wytnyt Posted April 28, 2013 Share Posted April 28, 2013 a good paste is essential to good proper cooling,proper application and adequate cure time [if needed] will produce the best temps possible for heat transfer Link to comment Share on other sites More sharing options...
J_abellana Posted April 28, 2013 Author Share Posted April 28, 2013 there's definitely bad contact going on. It might be the back plate since this is the second time I've had to reseat it and it's showing the same pattern. http://i519.photobucket.com/albums/u357/citizend13/dc69db4a-aef5-4e36-94b8-15194e6ed604.jpg:original Link to comment Share on other sites More sharing options...
Speed Posted April 28, 2013 Share Posted April 28, 2013 Perhaps, but the viscous grease will exhibit that sort of "tearing" when it is pulled apart. So, not exactly a good test to see if it is making full contact. It does, however, appear to be getting all the way out to the edges, so most probably is good--if applied correctly in the first place. What is your CPU core voltage (Vcore) when at idle and under load? Use CPU-Z to find out. If it's too high, your temps will be unnecessarily high, too.

I've tried reseating it again. this time the idle temps average at around 36c (higher) but the load temps seem to be better. they average out at around 69c- 73c whereas they got to 75c-78c Vcore at idle (1.601 Mhz) is 1.021 Vcore at load (3.9 Mhz) is at 1.296 -I havent touched them at all so I assume they're the motherboard's stock voltages. I'm not familiar at all with the Ivy bridge voltages. Are they too high at load? Link to comment Share on other sites More sharing options...
Speed Posted April 28, 2013 Share Posted April 28, 2013 OOOoooookay. You said "reseating it". Did you fully remove the previous grease, clean both surfaces and re-apply according to Arctic Silver's instructions? My Ivy Bridge CPUs run at 0.904 idle and 1.200 load, clocked to 4.2GHz. Temps are 27C-33C idle and 55C-58C initial load--reaching 58C-61C prolonged load. Link to comment Share on other sites More sharing options...
J_abellana Posted April 28, 2013 Author Share Posted April 28, 2013 Yes, I removed previous grease, wiped it down thoroughly... though I applied the thermal paste using the "pea" method or whatever they call it. I was also using a deepcool z3... It was the only one I could get my hand on on short notice. You think switching to a higher end thermal paste would make a difference? Though a factor may be that I'm using a small MATX case. (cougar spike) though it's ventilation is pretty good for a tiny case. I did another hour thirty minutes in prime, and the 4 cores averaged 74c... ambient temp (outside the case) was around 26c-27c. Is this too high for a stock i7-3770 on H60? :confused: Link to comment Share on other sites More sharing options...
Bryman Posted April 28, 2013 Share Posted April 28, 2013 Dude try 1.15 to 1.2 volts for 3.9 ghz... 1.3 is WAY too high that's for like a 4.5ghz clock I don't know if it lets you adjusts voltages on a non k CPU though Link to comment Share on other sites More sharing options...

I'll look if it's adjustable. Link to comment Share on other sites More sharing options...
J_abellana Posted April 28, 2013 Author Share Posted April 28, 2013 I think I found the culprit. In the bios settings, the turboboost feature was left at auto. Somehow, this meant that at full load, all 4 cores ran at 3.9 Ghz instead of 3.7 when all 4 cores are active. although now that I think about it, an additional 200 Mhz wouldn't hurt. What do you guys think? Link to comment Share on other sites More sharing options...
Bryman Posted April 28, 2013 Share Posted April 28, 2013 can you adjust the voltage on the non k one? if you can turn voltage waaaaay down if you cant try 3.5ghz and it should fix the problem... you should of gotton the k version :( Link to comment Share on other sites More sharing options...

I figured since I wasn't going to oc it anyway I figured I'd save a few extra bucks. I was just confused with the gigabyte settings I'd never figured the default settings out of the box would have the turbo frequency running at 3.9 Ghz for all 4 cores. It just didnt jive with other "stock" temp measurements found in the net. Link to comment Share on other sites More sharing options...

Is this too high for a stock i7-3770 on H60? This fairly decent temps, considering that you are using mATX case where airflow is limited compared to a Standard ATX case (more space). Did it make a difference when in temp when Turbo boost is disabled vs auto? Link to comment Share on other sites More sharing options...

Did it make a difference when in temp when Turbo boost is disabled vs auto? The Cougar spike case has a fairly decent fan setup. 2 x120 fans blowing directly into the mobo and the videocard. one 120 out back. one 120 up front. Still cramped though so I'm pretty sure there would be some hot spots where air is stale. when I enabled the intel specified turbo boost and disabled the pll overvoltage (3.7 ghz when all 4 cores are 100%) temps hovered around 56-60c per core after 1 hr of prime. I pushed it up to 3.8 and it hovered around 60-64 per core. so it's kinda consistent. One thing I did that probably made the most difference was replace the pull fan (it was a no name 120 fan..) I pretty much got the performance in line to what most are getting. My one complaint is there was something weird with one of the bolts connecting to the backplate. I could see that it was around an mm higher than the others. I flipped them over and they evened out. It probably wasn't threading all the way in.

Corsair Employees RAM GUY Posted May 8, 2013 Corsair Employees Share Posted May 8, 2013 just one question though, do I really have to turn off the pwm control for the pump? would it be fine running full on all the time? Pump should be running at a constant rpm all the time. Lowering/Increasing the rpm of the pump may affect the cooler's efficiency and probably cause damage to the pump. I'd suggest that you keep it around 4200rpm. Link to comment Share on other sites More sharing options...
