E8500 temps and heatsink questions

Forum Overclocking : CPUs E8500 temps and heatsink questions

Hello all. I have been thinking about getting into some overclocking, but my stock temps seem a bit high to me. I'm running an arctic cooler 7 heatsink, but my idle temps are 33-35 in one core, and a solid 39 in the other according to real temp. According to CPUID they are both 39. Under load in prime95 I hit about 55-56. Do these temps seem too high to attempt an OC?

i'm running my e8500 @ 4.275ghz 24/7 folding @ 100% core usage
runs at 62c max..
it runs at 27c core 0 and 36c core 1 when doing nothing, depending on ambient temps
it runs fine @ 4.5ghz but id rather hold it back a little whiles its folding 24/7

i believe the max temp is 72c but i may be wrong

THose temps are kinda on the edge but are generally fine.

I just OC'ed to 3.8 using 9.5x400, and have my voltage at 1.25. I saw a 63C temp in realtemp when doing the sensor test. This seems really high to me. Would a better heatsink like a Tuniq Tower 120 help this a lot, or am I just doing something wrong?

Edit: Ugh, just hit 65 in Prime95 small FFTs in about 2 minutes, looks like I'm just gonna have to back down till I get some better cooling going.

They are staying around 41 idle. But that's with the multiplier being lowered to 6x according to CPU-Z. I have speedstep disabled, so I'm not exactly sure why my processor is doing that. I'm thinking I should reseat the heatsink.

Look for C1E in bios and disable it(if you like). C-states and speedstep are two different technologies even though they work in a similar way. You can try reseating the heatsink(and use quality thermal compound)

Was it a brand new Artic Cooler 7 that came with the pre-applied thermal paste?

It was indeed. Looking back I regret not cleaning it and using some AS5.

If that's your baseline CPU temps at stock settings, they are high. I don't know what your ambient temps are, but my idle E8400 at stock speed and vcore of 1.20 is around 35C and load around 42C. That's with a room ambient temp in the dead heat of summer around 79-80F which is comfortable in A/C. Overclocking to 4.0GHz and pushing vcore up to 1.336 yields a load temp of 55C. Pushing up to 4.4GHz with vcore at 1.455 produces a load temp of 64C, of which I obviously do not run all the time. The sweet spot for this build seems to be 4.2GHz at 1.39 yielding a load of 58C.

I did reseat everything after about a month for burn in and temps dropped a couple degrees. Also, I did some cable re-routing for maximizing airflow and that help with another couple degree drops. Tinker around with that thing and you'd be surprised at the results.
