OK you guys. I got interesting facts after 3 weeks of usage.
Without changing anything on my rig, I see small drops in temperatures every week. If you read my previous post I was having the same overheating issues with my 4790K as everyone else. Now I believe I have none. MAGIC …I don’t think so.
First of all I run the IntelThermalTest v0.1 tool (BIG THANKS to karwos). Again let me remind you I don’t use intel stock cooler. I use a Corsair H100i.
Here are my results:
this is about half way...
almost at the end...
and final results.
As you can see my temps never exceeded 52C. The same results i get with OCCT and AIDA64. The only program that gives me higher temps (about mid 80's) is the latest version of Prime95 which is known to cause this with the use of AVX commands. Let me stress that the test was done with 22c room temp and all the fans to 30% (the case was almost silent), so temps would be better if i used the 100% of the cooling capacity of my build. But i don't think this is the point here.
Anyway what has happened here is in my opinion what other users are referring to as heat spreader settling in. If the gap between heat spreader - die is bigger than it should, and this is causing the overheating, maybe then, if you apply adequate pressure with a good cooler, the heat spreader starts pushing the glue and "settles in" closing the gap between them. But that takes time. Because many of the guys here RMA the CPU almost immediately, they don't give the CPU the time to heal itself . Offcourse this doesn't change the fact that it's still a manufacturing error. Anything that comes out of a production line should work right away and without burn-in time. Also i am pretty sure now, that stock cooler is useless, and should be used, only if the CPU is used with turbo-boost disabled and ambient temps don't exceed 23C. They should have never given the 4790K bundled with a cooler, something which is misleading, and forces anyone buying this CPU spending extra money for aftermarket coolers.
Closing my thoughts let me say that during the test everything on my MOBO (GA-Z87X-UD5H bios F10c) was on auto.
