Hello all,


I plan on overclocking the 4670k to its max. on air. Haswell runs hot so..

Is it possible to delid the i5 4670k and mount (with TIM) the heatsink of an aftermarket air cooler directly on the CPU (without the lid)?




Thank you!

I don't know if this is just me or is it pretty badly worded :??:

Anyway I think what you are trying to say is, is it possible to install an aftermarket cooler with your CPU?

Answer is yes you can, but the size of your case is also taken into account when it comes to sizes.

But for your answer, you can install any aftermarket cooler that you would like.

If you are talking about removing the meatl cover on the processor that carries the Intel logo and processor ID, I would think not. You can pretty much bet that Intel wouldn't put it there is it wasn't needed simply due to the expense. I'm no chip engineer but my guess is that there is a lot of thermal engineering that goes into that part.

On the other hand, if you want to try it go for it and let us know. Just be prepared to buy another CPU if your idea doesn't work out.

^alannm37: he's asking if he can remove the metal lid, the IHS, the big square part on a CPU where you'd place the heatsink on (hence delidding. read it up.), and replace the internal TIM with a much better quality TIM on the CPU die.

not a delidding expert, but considering it's been done before, i say plausible if you're willing to take the risk and take all that prep time: http://forums.anandtech.com/showthread.php?t=2285595

Yes. I haven't heard of anyone doing it with an air cooler though. The main problem I would see is that a good air cooler has a very high mounting pressure and so you would have to have the perfect installation or you will crush the core. Even perfect you may crush it.

It would be an interesting experiment, but i wouldn't do it myself. Havent got the money for it either :p

How i understand, is that he removes the big gray thing on top of the cpu itself, puts thermal paste on top of the cpu, not the gray thing, and mounts a heatsink directly onto the cpu - I would say, pretty risky, but if you got money to blow, and want a wonder chip with great temps, you should try it.
Not sure if it would work, or kill the cpu.
Just remember, it is totally up to you, if you wanna try it.

I have done this a couple of times (deliding older chips) but you don't want to remove the IHS alltogether you should do it and replace the TIM and reseat so the IHS is closer to the die then the cooler is mounted the same way as normal.
It is risky if your not careful and you can kill your chip. Mounting the heatsink to the die is very risky can easily crush or and won't improve temps much more than a proper delid
I believe this will also void your warranty so if you kill your chip you will have to buy a new one.

Yes, this is exactly what I intend to do :D.
I've only read about doing this 'experiment' with a water cooler, there is nothing on the web mentioning an aftermarket air cooler..

Also, why would it crush the CPU? It's almost the same, but without the little gray thing.. Does that little gray thing prevent the CPU from being 'crushed'?

Does the IHS somehow prevent the CPU from being crushed if it's in between the die and the heatsink of the cooler? Otherwise the heat could just transfer directly to the heatsink of an air cooler. Wouldn't this be far more efficient?

Thanks in advance!

Haha, yes.. I am concerned too :p. The last thing I want, is a 'crushed' CPU...
Maybe I'll give it a shot when I've got a little more info at my disposal..

Yes the IHS helps to spread the force of the mounted heatsink over enough area to avoid damage to the die it can be done though. The IHS actually adds very little resistance to the heat transfer and direct die only shaves a few degrees off of a proper delid. it is the space intel leaves in there in the stock configuration to help make them more durable during handling that prevents heat transfer. See this thread they explain it much better than I do all your questions are actually directly answered and most all with experimentation lot of reading though.

Still applies with Haswell

Alright, think I'm just going to delid it 'the normal way' then :p.

Thank you!

Yes, it is just you. He worded it perfectly and you totally didn't get the point.
