Just done some overclocking on my i5 760 yesterday, and after spending a day on it I think I'm going to leave it for the time being, as I couldn't get it up to 3.73GHz without upping it more than 2 voltage increments, and it's pretty hot as it is.

Running Prime95 to test it atm, but it passed 10 runs of IntelBurnTest.

It's quite a warm day, and I'm using the SG03 case so really hardly any airflow at all. With IBT I hit a max of 84c, and with P95 I've hit 82c so far.

I'm running at 3.71Ghz @ 1.16875v, 1.19v VTT, RAM @ 1770MHz 1.6v 11-11-11-27-2.

Does this look alright? Would this cause any problem long term? Or should I run it lower.
 
I ran my i5 750 for 2 years at similar temperatures but with much higher voltages (1.375).

I'm not able to guarantee it'll be fine because 80c is fairly high for a 24/7 overclock, but it didn't kill mine, and it was in a higher-risk scenario than yours: High temp + high voltage is worse than just high temp.

Maybe turn it down a little if you're paranoid...... but from my experience, they can run at 80-85c long term without any problems.
 
Seems like it's not too bad then. I think I'll keep it as it is.
Sun's gone down, and I wiped the very little amount of dust gathered on the grills/dust screen and it doesn't seem to go above 78c on P95 now, so should be fine! Thanks.
 
They're fine with up to 90c and 1.4v, the only thing that will accelerate with high temps + voltages is the chip's degradation.

It's hard to believe that you've got such high temps with this little voltage though, it's stock, pretty much.

What does it get to under load, I suspect you have some super high LLC turned on and the real voltage is higher.
 
Had to rollback from 3.71GHz as I couldn't get it stable atm.

3.65GHz, 1.15vCore, 1.17v VTT
1740MHz 1.6v 11-11-11-27-2

10 runs of very high IBT is stable.

CPUID reported 1.18v when it was on load. The side panel is off + psu is out of the case (I had to reset BIOS earlier), and max temp was 80c.
 
Is it blend or small fft that is failing prime?
What cooler do you have?

I have an i5 760@4ghz, load line calibration set to 1 in bios and 1.300v. Temps get to max 83c in IBT and max 75c in Prime 95 small fft. Blend temps are a bit lower, around 70c.

I also have 8gb kingston hyperX (genesis grey)

24 hour prime stable and maximum IBT stable. Are you running IBT on max stress level?
My reported load temp is 1.248 V
 
I wouldn't worry about the heat personally on midrange cpus, my i5-750 @ 3.87 runs around 55C in Windows and shoots up to 90C under heavy load, although this is with around 1.34v.

My view is hammer your cpu (within acceptable voltage levels) and if it's burnt out in 4 years then who cares, time to upgrade anyway :)

In terms of crashing under prime that is more of a concern, by guess is your voltage is too low, mine wouldn't be stable at 1.15v either.
 
Been running this 24/7 (literally, PC never goes off) for 18 months:

i5 750 @ 4ghz - 1.312v under IBT load (1.3625v bios LLC lvl 1)
40c idle
70c IBT

I can knock 10c off each when running at 3.7ghz.

Megahalems cooler and a single GT1200 fan spinning at 50-80% speed.

A high-end cooler makes all the difference.
 
It was failing small fft, but I left it at 3.65Ghz now.
Just coming up to 12 hours on prime (blend) and seems to be doing well. 75c max and 1.18v max voltage.

Same settings as my last post.

I was running IBT at very high.

Cooler is the Corsair H50-1 with the stock fan so not the best fan. (EDIT: Wait.. no I lie, it's not the Corsair stock fan, it's the case fan that came with the case; has the little golf ball things) I was going to get the Apache Black but never got round to it in the end. Case is the SG03-F, and if you're not aware of the layout, the PSU is bang in the middle of the case sideways, so pretty much blocks the air flow.

I'm going to leave it as is for now. Reasonable overclock at decent volts, reasonable temps on prime, and seems stable. I'll keep blend in prime going until 20+ hours or so.

My CPU score with the Windows Experience Index went up by 0.1! Awesome! :p

Max IBT is more hardcore than prime small fft. Give it a try and see if you can get it to blue screen!

I had an H50 on my Q6600 and temps got higher than the freezer 64 pro I am using now. Maybe the radiator was blocked or something
 
Get a cheapo fan around the same rpm as the other and do a push pull exhaust setup.

I ran with the stock Corsair fan that came with the h50 (~1700rpm) with a GT-14 Gentle Typhoon (1450 rpm) for a year or so. Then upgraded to to GT-15's and the difference was under 10'C at load, but much quieter.
 
Not really much space to do push pull, and I can't swap for an air cooler due to the psu being in the way. I'll be gaming tonight, so I guess I'll see what temps I hit when gaming.
 
It passed IBT and prime, but every so often the system freezes and hangs, and I have to shut it down by switching it off by the psu. I've already bumped up the vcore by 3 increments but it's still happening. Do you think that I should just keep upping it until it stops freezing, or do you think it's another problem? Possibly not enough volts on the RAM?
