2600k Very high temps @ 4.5 GHz - Page 2

Reseated and same issues. This was a painful reseat as I had to remove the entire motherboard as the mounting bracket came loose from all the reseats.

I also tried using the stock cooler that came with the CPU @ 1.32 vCore, 4.4 GHz, and the temps immediately shot up to high 80's/low 90's when running Prime95 Blend.

At this point I'm incredibly frustrated and think I'll just exchange the CPU as I'm within the first 14 days of purchase.

honestly i think people overhype the 212+. Ya your temps are a bit high but i reach low 70s on an i5 2500k at 1.25voltage 4.2ghz with a 212+. You might be better off just going for a higher end heat sink as its probably not your CPU.

I'm running a Hyper 212+ myself and don't have them kinda heat issues.
I'm running my 2600k with HT on at 4.8 1.4125 and have never seen temps higher than 78c running prime 95.

What case are you using?
Are you running a single fan on the heatsink. If so I would highly recommend a push pull setup with 2 higher cfm fans.
Also run your fan at top speed and make sure the exhaust fans can move enough air out of the case so your not recirculating warm in the case.

I'm using a Cooler Master Sniper which seems to have very good circulation. Yeah I'm running a single fan on the HS. But even so, don't my temps seem way too high?

One other thing, during the Prime95 Blend test, temps stay somewhat reasonable (max 81) @ 4.4 GHz, 1.32 vCore, for the first test, which takes about 15 minutes. Then suddenly at about the 15 minute mark, that's when the temps surge into the 90's.

Your 212 isn't the best cooler on the market, but it should be performing better then that. With your voltage under 1.4v, you shouldn't be getting that much heat with your 2600k. Something is obviously wrong with your overclock if your getting temps that high, I would start over. You should be able to get to 4.6Ghz+ easily with 1.3v and keep your temps under 80C. 85-87C is not a temp you want to run 24/7 obviously.

Couple of ideas:

Why is your LLC @lvl 1? I would try setting it to 3 or even 4 and your temps will drop. Lvl 2 is as low as I go on my 2600k and that will get me easily to 5Ghz+. At 4.8Ghz I use lvl 3 and my temps are in the low 70s under full load. At 4.8Ghz when I set my LLC to lvl 2, my temps rise to the upper 70s.

You can also increase your short/long term to 500/500 and see if that helps stability and heat.

I've messed with my Z68 board and my 2600k a TON and I can honestly tell you even the smallest settings in the bios can make a huge difference in stability and/or performance and heat. I run a Corsair H-60 with custom push/pull fans on my 2600k, but even then I don't see that kind of heat until I approach the 5Ghz mark with my chip and that's over 1.4v on the chip as well. I would start from scratch and give us some stock heat numbers, then we can see what the problem is.

totally agree. 212+ is good, but might not be the best in that price range. people now just indulge in it.

i have one 212+, another one cnps 10x, cnps 10x is much better than a dual fan 212+ in my computers.

strongly suggest you go to exchange cpu and motherboard.
it might waste your more time to figure out what is the problem.

Ok, so I set my UEFI back to factory defaults, and have been running Prime95 Blend for the past 22 minutes. Max temps are:

57-64-65-60

Max vCore drawn: 1.21 V

Pretty high for stock clocks no?

it should be ok, mine 2500k is 1.26v full load at stock speed. i saw some report of wrong temp use it87 sensor, but asrock is ncct sensor, should be no such problem.
