Hello folks,

I have upgraded to a Arctic Cooler Alpine 7 Pro. Couldn't choose anything bigger due to not having the space in my mAtx board/case.

I have the CPU at 4.3ghz with the stock voltage at 1.044v
Idle temps are 36c
Prime95 run for a few mins reach up to 85c
When doing a Benchmark test the max temp reaches 68c

I'm new to oc, but have been reading a bit and know that some may want to do prime95 for 24hrs and get temps under 70c, but for that I might have to lower the ghz, since I can't upgrade to a better cooler at this time.

My question is, am I safe to use the system at 4.3ghz?
I don't think I will ever use the system under the conditions that prime95 puts it through to get that hot at 85c.

I will mainly use the system for Pro Tools to record and process audio.

I could keep my eyes on the temps while using it, but wanted to hear what you think as far as my current setup at 4.3ghz.

Ps: I've read that Intes states that the 72c temp they put as max is really a temp they expect to be normal and that they say the CPU could reach 90c and still be ok. Not so say I'd like to run it at 90c for long, but since once typically just briefly uses max cpu if at all, then being under 90c in my case, might be just fine. Thoughts?

Incorrect mounting of the heatsink or poorly applying thermal paste would cause this, as would very poor case ventilation.I'm in a similar situation (I botched the thermal paste and probably the mounting) and Prime 95 gets up around 85C quickly, yet in actual use my max has been 68C, 62 average for demanding games. You'll just have to keep an eye on it.

Everyone has an opinion on max temps and vcore. The real question is, when would you replace the CPU anyway? If longevity is a concern, I'd keep vcore definitely under 1.4v, preferable not much over 1.35, and temps at 75c max under normal use, or it will shorten CPU lifespan.

So you know, Intel stated that TCase max is 72.6C, and exceeding it will decrease the lifespan of the CPU...

So you know, Intel stated that TCase max is 72.6C, and exceeding it will decrease the lifespan of the CPU. TCore is what temperature monitoring programs use. According to CompuTronix's findings (http://www.tomshardware.com/forum/278083-29-core-temps-temps-tjmaxx-2600k-real-temps) TCase ~73C is equal to TCore ~78C.

4.3 at 1.04 vcore seems like very, very low vcore, which is great if it is actually stable. Prime 95 runs ~60 tests when blend test is selected, and can take 17 hours+ to complete. Because your temps are so high, I wouldn't do that. IMO a good indicator of system stability would be to run the custom test in Prime 95 with 90% of your memory. If you are unstable, you'll likely know it in less than 5 min, but I'd run it for 15 min for good measure and then run a gaming benchmark or the equivalent, for example FutureMark.
