i7 860 Running way too hot. Hyper 212+ Not Good Enough?

post #1 of 39
Thread Starter 
So I OC'ed my i7 860 to 4.0 using 1.45V and the thing ran up to 91C on one of the cores after playing 15 min of GTA4.

It wasn't running prime or anything... Just GTA4. makes the games ALOT more smoother but can't be gaming at 91C... also lol at the fact that a 1.2 OC also gives me 1.5 fps more.

Ambient temp is 27C. That might be sorta of an issue but really doubt it.
I have decent airflow in the case as well. not the best, but certainly not the worst.

Is my Hyper 212+ just not cutting anymore? I think I'll reseat tomorrow and hopefully temps will drop but jeez...

Any good solutions to an alt HSF? I really don't wanna shell out $75 for a D14 or Silver Arrow but if it'll kill the temps then...

Any mediocre solutions that'll keep this cpu under 70C for a decent price?

Thanks!

I'm pretty sure a Corsair H60 would do the job for a decent price. If you want to spend more though, grab a H80 or H100.

mayb your just unlucky in the silicon lottery, have a look at the NH-d14 or corsair h80

Lower the voltage. 1.45v seems high for only 4.0Ghz OC. You should be able to get it to run at 1.34v-1.38v IMO. Temps should drop quite a bit also.

1.45V is way to high.

Max spec for these chips is 1.40 with VDroop (no LLC).

Max temp is 72,7 degrees for TCase, so somewhere in the 80s for the Core.

If the high temperature is purely due to the capacity of your 212+, then I am afraid that upgrading to a top-of-the-line cooler like NH-D14 or Silver Arrow will not be significant enough to bring the temperature down from 91C to sub-70C under full game load.

Even with such an upgrade, you will probably see a drop of 5-10C temperature drop (accompanied by an acoustics improvement). But dropping below 70C is highly unlikely. And, I think even a H100 would have a very hard time to even come close to that sub-70C mark.

Rather, I suggest you to focus at reducing the voltage as it is the chief factor for high temperature. As pointed out above, 1.45v is (too) high.

Additionally, I strongly suggest you to turn off HT. With HT off, you will see noticeable temperature drop as well as easier to overclock at lowered voltage.

What do you mean by max temp?

What's the point in paying extra for HT, and then turning it off? headscratch.gif:

@stupidcha 1.45v on a i7 860 (which inherently run hot) is far too high for both the chip and the 212 Plus. If you can't get to 4Ghz with 1.375-1.400v (LLC off) then back off the clock speed.
