Core 2 Duo E8400 Temps?

I just picked up an E8400 to go into an HTPC that I am assembling, and I was wondering what type of temps I should expect. Is it possible to passively cool one of these with a moderate amount of airflow, or am I just asking for trouble?
 
If you really want silence, your best bet is to simply buy a standard cooler and mount a quiet fan on it. You'll get much better performance than a passive solution while still maintaining noise levels low enough that you won't even notice the fan. As for temps, monitor using Core Temp or Real Temp, and anything in the 60s or under would be normal (under load). Your CPU can handle temperatures up to 100C without trouble, but it would be abnormal for you to see temperatures over 70C using the stock heatsink or a silent cooler.
 
I have a Zalman CNPS8700 + E8600 in my HTPC with the fan set on the lowest setting, and it is very quiet. Not silent, but very quiet. Without the fanmate, the fan is loud at full speed, so definitely use the fanmate if you go with this cooler.
 
Depending on ambient temps somewhere around 30-40C idle is good. Load using Prime95 should NOT exceed 70C IMO. Max threshold for this chip is roughly 100C.
 
I was hitting 75 in prime 95 load on stock heatsink without oc on my e8400. I think people have some misguided perceptions about the e8400 chips. After market heatsinks should keep it a lot cooler, I know my zalman 9900 does. I'd say just watch that it doesn't exceed 75c.
 
For Core 2, the max T juntion temp is 100-105 C think, If you go over 90 C there you in trouble. For a Core 2, nice temps are anywhere from 60 C and below, mine typically hover aroudn 42 C on a Core 2 Quad. Your manual should say specically. The thermal spec on this model is 72.4, but not sure what they are mesuring there (on die?). If you always get high temps , check your Thermal paste spread against Artic Silver's methods on their site, or consider a better CPU cooler. Try CoreTemp out to get a decent reading.

Tjmax is 100C for all non-Extreme Edition 45nm Intel CPUs. For 65nm chips, it varies. And temperatures 15-20C or more from Tjmax are perfectly fine; anything around 85C or below even on a 45nm Core 2 Duo or Quad is perfectly alright.

The thermal spec is based on Tcase and is completely worthless as far as we are concerned when we measure temperatures using software.

Those stupid half-height Intel coolers that come stock with the E8400 are dangerously small if you ask me... The don't even have a copper contact pad or anything.

The stock coolers are perfectly suitable for what they are designed for, which is to cool the CPU when it is running at STOCK speed.
