Please help me which cooler to buy for an i7 4790k?

[Stonehencs]

Hello! 

 

I have an i7 4790k processor and a BE QUIET! Pure Rock 2 cooler. I noticed that 2 of the 4 cores are above 80 degrees when running at max and the rest are around 60 degrees. And all the screws are tightened.

Can you help me with the cause or what cooler to buy instead?

What thermal paste are you using? 

 

How's the thermal paste spread when you remove the cooler? 

[WereCat]

You don't need a new cooler, you need better thermal paste application and to mount the cooler properly. 

 

Also make sure to not overtighten it as you will bend the board and make worse contact with the CPU.

Delid the cpu and change the garbage dried up tim for prefferably liquid metal but even thermal paste will work fine, ppl have done pretty high ocs on these chips even on basic ass hyper 212s, a pure rock 2 should do better than a bog standard h212

 

What oc btw?

I re-pasted with brand new MX4 and didn't tighten the screws as much but it didn't get much better. For some reason the front core is still around 83 degrees. Try again with the screws tightened even less? Or what do you think I should do?

Dont loosen it much, the point was to make the tight even on all screws and also not too tight but tight enough.

 

Anyways, Haswell suffers from having high temps because of how the IHS contacs the die, that's why people used to delid them a lot. This does not look like a cooler issue to me since you would see all cores to run a high temp during full load and not just one or two. But the delta here is just too much.

What motherboard and stress test are you using? Are you running default bios settings?

is 4790k overclocked?

 

my 4770k on stock with Scythe mugen + arctic p12 barely hits 75c

Just to clarify
How's the cooling of the system ?
What is your PC Case ?

I have an Asus 85M-E motherboard and everything is on factory bios, I just increased the PWM of the processor fan to make it spin faster.

The video card is running around 60 degrees under full load after I re pasted it.
The computer case is a Genesis 700

Everything in the machine is air-cooled

if u remove the side panel does the cpu temps go down?

[Stonehencs]

I delidelt the processor and this is the result under full load.
