High idle to load delta...what next?

[elwoodh]

Idle:
Coretemp: ~40C
TAT: ~42C

Load:
Coretemp: ~71C
TAT: ~70C

Load using TAT, 100%.

Orthos (large FFT) is ~26C idle to load delta.

Um...time to reseat the heatsink? Time for a new heatsink? (I have a Zalmann 9700 LED w/ Ceraminique)

Ambient = 22C

E4300 @ 3.2ghz (vcore 1.425)
2GB DDR2 PC 5300
GIGABYTE DS3
CORSAIR HX520
PNY 8800GTS

It's definitely time to do something. I think you should try to reseat the heatsink first and use arctic silver 5 instead of ceraminique. I heard that silver 5 works better than ceraminique. Do you have back exhaust fan? Also check to see if the heatsink is properly on the CPU and all the screws are tighten. I have the same motherboard, and I use zerotherm BTF90 with arctic silver 5. My E6600@3.0GHz is at 27C idle, 37C load, 25C ambient. Good Luck.

Yes, I have a back exhaust fan. One 120mm blowing out, two 80mm blowing in (one in front, one on the side).

e4300 runs hot it is based on a laptop core. It is not uncommon for laptop cpus to run in the 80s-90s. Check your degrees to throttle via core temp. E4300 doesn't throttle until 100C.

Update: Well, I ended up reseating my HSF about three times, but didn't see any concrete difference in temps.

I rolled back to stock voltages and clock speed, and temps were idle, ~33C, and at 100% load in TAT, ~50C.

So, I ended up reducing my overclock to 3.06ghz (and vcore down to 1.375), and now my temps are ~39C idle and ~65C load.

Better, still a high delta, but better...

I also resat the HSF outside of the case to initially check temps, so I know it's not a ventilation issue, because the 30C+ delta still occurred at 3.2ghz.
