I7 860 overclocked to 3.80 GHZ HOT?

[fastreaction]

Hello,
I have overclocked my i7 860 a week ago.
Here are some pictures.

As you can see, I have run Prime 95 custom blend with 90% of ram for 13,5 hours and intel burn test on maximum with 50 passes. HT on.

However, the last days the weather is pretty hot (27 degrees) so I turned off HT. When on load it can even go over 80C..

I re applied arctic silver 5 but it seems like it didn't make much of a difference.
My cpu cooler is a cooler master V8 and I have a HAF X case with 5 case fans. 2 on the top, one front, one sideways and one on the rear.

The weather usually isn't this hot. Is 78c even normal on load? Seems pretty high for me.

The temps just do not seem right. Any help?

Thanks.

when it gets hot outside just try not to load it when you can, your chip will be okay running over 80C sometimes, but it will shorten the lifespan if it runs that hot too much
