How bad an idea is running this overclock (5 GHz 1.47v 2600k on NH-D14) 24/7?

[YogevSkill]

See topic - I recently got my 2600k up and running with a noctua nh-d14 cooling it. I have it at 5 GHz (simple x50 multiplier) with 1.465 volts on an ASRock z68 extreme7 gen3 board.

It is not really prime95 stable... I think it may pass hours of testing, but small FFTs (specifically 8k) make it get WAY too hot... it is between 90-95C during that test (which is 10-20C hotter than other tests make it). I'm not willing to really run the test for hours to see if it actually survives.

However, during other prime95 tests, 3dmark11 physics loops, gaming, etc, temps stay at 75C or less. Idle temps are 25-30C. So, I'm thinking that this is a stable clock for my purposes, since I don't do anything more CPU intensive than gaming. Is this a terrible idea? I do love the idea of a 5 GHz CPU, but if it means that the chip is only gonna last like a year, I'll scale it back to 4.7-4.8 and see what the temps are.

Thanks.

Too Hot friend 96c your lucky your CPU isnt Smoking.

for benchmarking it "ok" but putting that kind of load 24\7 with air coolling on the 2600k will be its demise.

so lower the Voltage unless you want to buy a tombstone.

you could turn HT off. With HT off the temperatures do fall quite a bit, and you might also need less voltage to make the 5 GHz run stable. Maybe test it for a while. I'd not pass 1.4V with the Noctua NH-D14, but I guess you could maintain that if you really wanted too. The question is if you monitor your temperatures 24/7. But I feel it's quite a bad idea. It's simply too much for the Noctua too handle...

OMG, you either have your noctua on wrong, it's broke, or you are in a hot environment. My H100 which is similarly speced in cooling performance never gets above 80c at 1.5v 5ghz.

That's with the 2500k though right?

I reseated the Noctua a couple times and cooling performance was similar each time, so I'm either just doing something really dumb with my thermal paste or else that's just how the D14 does on a 2600k. My case ventilation is excellent, so that's not the issue.

I'm happy, for now at least, at 4.8 GHz 1.38V. My idle temps sit around 25-30C and my max load temps during gaming stay around 60-65C. Small FFTs in prime95 cause 75-80C temps, but I don't think I'll ever be doing anything on my rig that will cause a load like that.

4.8 sounds real good to me for a 24/7 setup.

My CPU running at 4.5Ghz (1.26V) in my HAFX with an H100 gets me 27 Celsius idle temps, and 60 under max stress tests. So... yeah, you're got too hot.

I would only overclock it to 4.5Ghz (1.2V) for 24-7 use but it's up to you at the end of the day if 4.8 GHz 1.38V. feels safe to you go for it

Why dont u disable hyperthreading, and put the Bus speed to 103.0 - 104.0 and the multi to 48 - 49 that sould give u alot higher clock speeds under alot less voltage...

Mhh my 2700k is at 4.8Ghz & Vcore 1.310 running max 55 degrees... Them temps are too hot for my liking but im pretty new to this overclocking.

55 degrees fully stressed? that's very good.

what's ur cpu cooler?
