Core i7-4770k running Prime95 hot. Is it safe?

why you dont delid? you have everything... just buy a tube of coolab and try a delid... temps are going to lower a lot....

sorry i ain't expert in this field, I don't get what you mean.

Search youtube for delid vice method or razor method.
I bet your hearth will stop for a moment.

I've tried about 5-6 times re-installing the heatsink, I'm pretty sure i did correctly every steps on youtube. And it's still to hot when i run prime95. I don't know what to do now
About the voltages, I saw in BIOS the CPU Input voltage is around 1.7

Dont run Prime.

i would slice it into two pieces if i do that.
Anyways, apart from "Small FFTs" test, everything else is okay. So I shoulnd't be worried right? I mean my average temp. is around 26-30c and Blend test is from 50-65 only.

It probably isn't good advice to tell someone who isn't even sure if he mounted his cooler properly to delid their CPU.

Give us a CPU-Z screenshot. The input voltage is fine at 1.7v, but your core voltage might be running too high. At stock speeds you should never hit 100°c no matter what you run.

Is this it? I don't know how to read this though.

seems legit ... my bad...

Yep, that's it. It looks fine in idle.
Now take another CPU-Z screenshot when you're running prime95 to see your load Vcore.

This is when I run "Small FFTs", temp is reaching 100c.

When I run "Blend test", temp is only 50-65, but still the same result in CPU-Z as above.

What temps do you get in actual applications you intend to use the CPU for?

xorbe · Dec 16, 2015

Small FFT is much hotter than Blend.

BarbaricSoul · Dec 16, 2015

You shouldn't be hitting 100'c at only 3.9 GHz and 1.29 volts. Did you plug in both the pump and fans? Is the pump working? How much thermal paste did you use?

peche · Dec 16, 2015

its hard to believe that with a decent cooler and thermal paste you hit 100C on a bench test… but runing a 120mm AIO watercooler getting 100c something may be wrong there lad, so much paste on CPU lid, unpluged bomb on AIO, dunno what to tell ya … but something may be wrong there…

BarbaricSoul · Dec 16, 2015

^my thoughts exactly, something isn't installed/hooked up correctly. The 2600k I had with a Corsair H60 crunching 24/7 while OC'ed to 4.5GHz @ 1.35 volts stayed around 70'c.

sneekypeet · Dec 16, 2015

What made me say the pump is not working was the 45degree idle temps on that AIO. Usually in testing, if I see that on an AIO, either the fans are not spinning, the pump is not running, or the plastic protector (sticker style) on the base was not removed. Demand of the test aside, you should be seeing higher 20s to lower 30s. Usually just a few degrees above ambient.

I just don't understand why there's different in result of 2 tests "Small FFTs" (100c) and "Blend" (65c). I don't have much understanding but still is it fine to work under this condition?
I've installed the heatsink for about 7+ times watching youtube. The fans are working i guess, I don't know if the pump is working or not since it's all black. I only use a small amount (like a BB bullet) of thermal paste and spread it over CPU.

When idle, it's 20-35. I guess it's okay?

alucasa · Dec 16, 2015

Like everyone says, something is wrong. However, it also seems like you will never hit the 100c under normal situation.

I wish I could take a look at your setup but that ain't gonna happen. You could just let it go.

may be conected to motherboard header named "CPUFAN" ...di you connect every single cable from the AIO unit?

I double-checked it. In bios I saw all the fans are working normally. I thought if one of them isn't connected it will alarm? I bought this new heatsink due to my old heatsink failing to start as CPU FAN shows N/A in bios (UEFI).
I tried working with Adobe AE and some heavy stuff but no problem happened at all.

Small FFT hammers the local cache / CPU is totally busy. Blend hits memory a lot, so the CPU isn't as busy, since it is waiting for memory.

In other words, I made some mistakes while installing the heatsink like thermal paste problem? Or something is wrong with my cpu?
Sorry for asking so much.

xorbe · Dec 16, 2015

I think you should find some help locally to more quickly evaluate what's going on.

Yeah, 1.3v is way too high for haswell, that is your problem. You need to get into your BIOS and lower the vcore.

MxPhenom 216 · Dec 16, 2015

@cadaveca and I have talked about it before, and he mentioned that coolers like the 212+ just are not enough for chips like Haswell anymore. Especially if you have intentions of overclocking. While I don't have experience with a wide range of coolers for Haswell, Dave and crazyeyes do.

Also I don't recommend delidding to anyone. Youll likely kill a chip faster from delidding, then if you didnt, not from the delidding process I might add.
