I just bought and put together a gaming pc... the cpu is i7-4770k and comes at 3.5ghz

My question is: after ovclocking to 4.0ghz and doing a stress test in 24c ambient, is 61c max temp OK?

Yeah your temps are perfect.....In fact you still have the headroom to overclock even further...:p

Not 100% sure on this, or how strong the new CPUs are, but I've had my CPU hit 95c consistently while gaming and I have never had it burnt out, which I know isn't safe but I'm sure you could max it at 80c. Now, my CPU is a Intel Core 2 Quad Q9000 so as I said, I'm not sure what the new CPUs can hit but 61c Max seems great, if not lower then what you could do. My personal experience thought though.

If you want to play it 100% safe don't exceed 65c.

Yes. You should have no problem hitting 4Ghz on stock voltage

Completely wrong. Haswell has a TJMAX of 100C. Why would you assume its only supposed to hit 65C?

Also completely wrong. It is in fact 72.72 c max.

So like i said, if you want to play it 100% safe, take 65c as max.

Off course you can let it run at 100c, but it will degrade faster. So it's not 100% safe.

The temp limit that is written is the max temps for the integrated heat spreader and not for the cpu.....get your facts right

Do a google search 'tjmax' for haswell and you will find out

What temps do you think you are reading? The tjmax temp means that it will shut down at that temp, the real safe temps are alot lower. I'm talking temps that will not wear your cpu at an accelerated rate.

That is what I am saying ....since the tjmax is 105c the max safe cpu temps should be around 80-85c.....You are being a bit too conservative by saying that it shouldn't cross 65c

Take in account degradation of thermal paste and dust building up, 65c is 100% safe, 80c isn't.

Thermal paste is pretty easy to replace and so is cleaning up the dust

Before i delidded i hit 95C while benching at 4.8Ghz with no crashes, stutters or any issues. The chips wouldnt have a TJMAX of 100C if they couldnt handle the heat.

Also 72.5 is the T Case temp, Not the TJMAX

Hi all

Re. my 4770k

I am too getting poor heat results all stock bios settings triple checked.....

tested with intel burn test which i have to stop short......

1st stock cooler 103c in less than 10 secs
2nd be quiet shadow pro sr1 up to 100c around 10 to 15 secs
3rd corsair h80i between 90c to 95c again around 10 to 15 secs

At the moment so i can work i am having to disable hyper threading and under volt the cpu to keep my temps down which is a joke ......

Surely this can not be right ...paying over £270 for this from intel i feel some what ripped off

Have you even tested an i7-4770k ?
If you did then you would know than with the stock intel cooler at stock speed this cpu goes past 65c during stress test.
Do you really think that intel would sell their cpu with a cooler that isn't safe to use with their cpu at stock speed?
