E8400 Idle temp

Got the e8400 cranking on my blood iron at 3.4ghz with 1.2v

Im idling at 40c right now out of my case with a tuniq tower and 2 120mm fans in the area. Wanted to know what others were getting....

Additional Comment:

Granted I'm on h2o, but I idle at about 21,28 (core0,1) with 1.2 vcore.

Additional Comment:

Its 64f in my house.

Additional Comment:

splave, what bios are you using?? I have the UT T2R, and I had to flash to the 1/09/08 beta bios to get the correct VTT settings and readings.

im on 11/7/07 bios and its working great

Did you notice your loads are closer to your idles than you would have thought? Like with my e6750 Idle was 26c and load was like 50c.

With vcore 1.2 it loads to 35ish from 21,28. With vcore 1.39 it idles almost the same, but loads to 50c.

I had the 11/07 bios when I put my 8400 in, but the VTT would read way lower than what was set (1.33 set = 1.18). The beta bios fixed that for me. I was also getting BSODs when I went to 3.8 or above, so now I am on a fresh install of Vista, so hopefully it was Vista screwing up....

Well this is a little strange. I just finished installing my E8400 a couple of minutes ago. I'm running at stock speed and getting 42C idle on both cores. I'm sure I applied the AS5 correctly. It just seems odd that I would be getting these temps at idle....

By the way, I'm using a Zalman 9700NT for cooling.

What's interesting is that at load, It tops out at 48C. So I get 42C Idle - 49C at Load. These temps are being measured by Core Temp 0.96.1

That seems too warm for only 1.08 volts..... Re-seat?

Thats does seem odd, you would think under load it would increase by 15-20 degrees.

I guess I could do that. I'll remove the HSF and re-apply AS5 again.

Well, I took everything out again and re-applied the AS5. Booted with Stock settings and am getting the same temps. BIOS shows CPU temp at 28C but Core temp shows 41C idle and around 48 under full load. I guess I'll wait a couple of days and see if the AS5 kicks in as I've seen in other posts. I'm gonna OC to 3.2 and see what temps it gives.

So your cores are higher then your reported CPU temp? What are you using to read your temps?

I'm going to do that just now. Funny tho, I was just on Overclockers forums and see a few postings for same thing. One guy reports same temps as me. 41 to 42 on both cores.

You guys will love this, I just Oc'd to 3.6GHz and temps read only about 2 degrees higher. 44C on both cores...hmmm....

Update2: Temps just dropped to 43C idle at 3.6GHz 1.160 Vcore

Yeah I re-seated twice, Im idling at 42c/39c at 1.2v set in bios at 400x9 with a Tuniq 120

load is 54 after 1 hour orthos fan speed on highest, any ideas? The tuniq is lapped by the way and I spread the AS5 with a credit card, very very small dot because of lapping.

Well, I'm running it at 3.4GHz @1.13Vcore and still idles at 42C. No change whatsover. I don't know if it's faulty reading or something else. Seems very stable tho, so I'm not really worrying. I'll try stress testing it some more and see what happens.

Additional comment: I applied the AS5 as instructed on web page - One thin line down the middle. Apply HSF and wiggle to spread the paste.
