What does it make on OCCT or Prime95? IBT has no real-world value IMO, it just makes stupid amounts of heat.
*EDIT* I see 69C with P95? That's way too much for stock.
Double check your mount and make sure the fans are blowing in the same direction.
What's your case's airflow like?
I checked my fans, they're blowing in the same direction.
My case's airflow is pretty good, 3 in take fans, 2 exhausts. I measured the temperature inside, it's pretty much ambient.
Motherboard bowed? Does your heatsink come with a back plate? Are you using it? Is it too tight?
You have the same temps as I do, except I have a B3, and I'm not lapped -- so something probably is up. Could just be luck of the draw and got a ****ty IHS solder job leading to abnormally high temps (for a G0).
I'm going to suspect a shwittty IHS solder job, since it's the only thing I've got left really.
The thing is... how do I fix it ? Keep lapping till I hit the actual HS on the die ? (I'm not kidding, I'm desperate)
