New i5 build, stock cooler @ 100% with high temps...

I just built my i5 system tonight, I have the stock fan running at 100% all the time. My idle temps using RealTemp are 40-44 without ANY overclock... Under IntelBurnTest, it got up to 81 before I killed it (as it exceed the 78 max recommended by Intel)... under Orthos (Prime 95) it tops out around 70-72...

I have a CM Hyper 212 Plus on the way and don't plan on overclocking until then, but don't these temperatures seem high for a non-overclock on a stock fan running at 100% constantly...

This is bios defaults as well with C1E, C-STATES, etc.. enabled.

Motherboard is GA-P55-UD4P... Ambient room temperate, not sure... the room is around 23, but my CPU is inside an armoire (that remains opened but is solid wood on 2 sides, vented on back). It's probably at least 25-30 where the case is... Case side panel is off (always is).

I think I found the problem. It was the 'auto' voltage setting on the GA-P55-UD4P motherboard. I went into the bios, set everything to 'Normal' instead of 'Auto', clocked my memory correctly, then overclocked the CPU to 3.2. Everything is fine and I'm running at 40C idle, and 70C load. Hopefully I can get to 3.8 when my Hyper 212 + gets here.

What voltage should I look to run at 3.8? It's nice to run stock volts at 3.2.

Even 70 C at load is a bit alarming! Hopefully you'll enjoy your Hyper 212+. It cooled my i5 750 off by about 22 degrees C with some artic silver.

Somewhere between 3.7GHz and 3.8GHz my i5 hit 70 at load with prime95 and a Xigmatek 1284 cooler.

You mentioned 3.2GHz overclock. This is hardly worth it with the i5 since turbo mode on top of stock speeds will almost get you to that speed when needed.

After testing at various speeds I settled on 3.5GHz for 24/7 use (63 degrees under sustained load).
