I'm wondering if my current setup has a performance issue. I'm running an E8400 at 1.4V in an open sided Antec P180 case. Original heatsink was a Scythe Ninja RevB. Fan was an Antec Tricool.
When running small FFT Prime 95 at high fan speed the CPU temp as reported by the on-die sensors was 60C.
When running small FFT Prime 95 at low fan speed the CPU temp as reported by the on-die sensors was 65C.
After researching about the poor performance of the Ninja Rev B, I decided to change it out for a new Thermalright Ultra 120 Extreme using the same Antec Tricool. The base was typical of user reports, but I tried it unlapped anyway. I also lapped it. Lapping did not change the result:
When running small FFT Prime 95 at low fan speed the CPU temp as reported by the on-die sensors was 60C.
I realize a 5C drop is a significant improvement, however it seems others with this heatsink as well as similar heatsinks report load temperatures quite a bit lower than 60C. I seems to me that I should be getting better performance. Running the fan on high only drops temps by a few degrees.
I'm using AS5 and applying as directed using a thin line. Whenever I remove the cooler, the TIM distribution looks very good.
Is there something else to check? Would lapping the CPU really improve things?
TIA
