CPU temperature i7-4770K

[jonathanwu607]

CPU: i7-4770K

MB: GIGABYTE Z97X-UD5H
Cooler: CM Hyper 212x

Case: NZXT H440 (stock fans + two extra exhaust on top)

 

Software: Core Temp

 

I've set the OC to 4.5GHz / 1.22v

The idle temperature after booting into OS is around 45~55 degrees, and reach over 80 degrees when running AIDA64.

This seems quite a lot hotter comparing to results on the internet.

 

I've tried both re-mounting the cooler and re-applying thermal paste a few times. but still get the same results.

 

Am I missing anything here?

Hmmm maybe thermal paste isn't covering it enough?

Just re reads OP..

 

If not the CPU just might be a bad one :///

[C0LL0SS0S]

Sounds like you are not a silicon lottery winner

[jonathanwu607]

Seems like I don't have the luck for lotteries...

 

but this temperature still seems quite unusual considering it's not a major over-clock?

[ind3x]

Sounds like you're simply putting too much heat into the 212x

[WereCat]

You are good... I have better cooler and can't go more than 4.4GHz with those temps.

[LogicalDrm]

Whats you room temp? Your idles are bit on the hot side. They should be more toward 40-45C.

[jonathanwu607]

Room temp is around 20C.

Ive got the h440 also, Sorry to say but that case is the worst thing known on earth for bad cooling, its quiet dont get me wrong. But for pulling air in through the front it is as bad as you can possibly get. Same for the exhaust out the top. Take the front panel off and see what you get then. 

Ive got a kraken x61 for my cooler. and without the front and top panels on my temps drop by 20c.... or take the top panel off and just put your hand behind the front fans. You can barely feel any directional air flow at all. Will be swapping my case soon tbh. gorgeous case. but air flow is terrible.

The 4770k has what is generally considered a lackluster thermal coupling to the heatspreader. You can choose to de-lid your CPU and attempt to correct this if you want. The cooler you have is approaching its limits however as it simply does not have the thermal mass to do that CPU at that frequency justice.

 

Before you go crazy make sure to check your test methodology. The FPU stress tests will reach much higher temperatures on these chips.

Thanks for the suggestion! Let me try taking front panel off and see if that's the issue.

(if that's the problem, will changing front fans work?)

 

and Yeah, I knew it has limited airflow before choosing the case. I am ok with the trade-off for its looks, just want to confirm it's within the reasonable range.

currently de-lidding is not something I can handle myself... guess that won't be an option for me...

 

Will 4790K be any better?(or worse?)

Any suggested CPU (air) cooler if i were to replace the 212x?

4790k has a lottery when it comes to how well the IHS paste is applied by intel.

Mines hits mid 70s under a h100i /w 4.5@1.184v. (mid 30s idle)

One of the issues addressed in the revision/refresh that produced the 4690k and 4790k was the thermal interface between the CPU and heatspreader. It's still not what I'd call a *great* solution, but it generally performs better. The 212 x/EVO is a bit lightweight for the 4770k, but with two fan might perform a bit better. The biggest thing is that you're lacking thermal mass and while the 4770k is rated at ~84w it seems to be quite a bit toastier than that number would generally signify.

 

I'd probably recommend one of the dual tower dual fan Noctua things if you're going to go for broke. At ~1.25-1.3kg I usually hesitate to advise using them though. If Cooler Master still made the TPC-812 I'd be more comfortable recommending that, but it has gone the way of the dodo. Also check my sig, I have links to some thermal paste roundups (something like 140 pastes) and their performances. If you'd like to cut to the chase though GC-Extreme is very good, quite usable, non-conductive and not too difficult to obtain.

 

Out of curiosity why are you avoiding de-lidding? It's much easier than people make it out to be and if you're looking at throwing several hundred dollars at your rig anyways it's not much of a gamble by comparison. I did mine with a razor since I didn't like the amount of force involved in the way people were doing it with a vice. I want an i7 so I was rather cavalier though...

Guess I'll have to either change to 4790K or the cooler.

Avoid de-lidding is just out of fear for damaging the CPU... but i guess i can practice with an old one, or with a ES sample first.

 

Anyway, thanks for the suggestions!

You're lucky mate. I can't even pass 4.3ghz
