Couple days ago I bought this CPU and noticed something strange around hole in ihs. It's not flat.



I have contacted with Intel support, and they tell me, that this is normal. So I inspected 3 CPU's in diffrent shops and they have the same issue.


sorry because of my bad english:)

Normal because it don't affect temperatures or normal because all new i7 have this?
My friend have the same cpu (probably different batch) and his is flat.

yea, that *is* strange. I finished a build with the i7-5820K just about a week ago. It didn't have that. From your image, it also looks as if that raises the surface a little which means the heat spreader won't fit securely. I'd look to see if I could return it.

Edit: Damn, I usually take a picture, but it seems I must have forgotten. I was going to add it here. Sorry.

My cpu goes to reseller service to veryfication, and they wanted to send it to Intel service. But it would take too much time so I call them not to do that and send it back to me.
As I said, 3 cpus, 3 shops - the same problem.

Wow, then as the other poster have said, it must work. Go for it. You have a 3-year warranty on the processor anyway. I suppose you know how to inspect a processor for legitimacy and not a rip-off? Google if you don't. THere are always a few shady rip-offs going around.

Honestly, I haven't a clue. All I know is mine didn't have that. It doesn't look smooth and I don't know how one would put a heatsink on it.

Heatsinks apply so much mounting pressure it would honestly not give a crap about a little raised metal. Thermal paste takes care of any possible little gap.

You just get a little paste under the IHS? Same result as if you removed the IHS entirely (yay for crappy paste in a 600$ CPU).

it is what worries me
Buying hi-end cooler makes no sense in this case (Noctua U14S - maybe mid-range, but still pretty pricey)



I thik it is the reason to use nonconductive paste.

You should be using non-conductive paste anyway. Conductive stuff is usually very high-end and pretty much useful to put who have like 4 big radiators in their system or do LN2 overclocking. For regular aircooling, especially with a good cooler, you won't need anything better than, say, Prolimatech PK-3.
