Just did my first mobo + CPU replacement, to an i5-650 w/ an ASUS board. Using the standard heatsink+fan. Also installed SSD and other new components.
In general things seem that have gone fine. Installed Win 7, system runs, and is fast. Problem is that CPU temps seem to be shooting up under load. Either that or temp. detector is wrong.
Haven't done any rigorous testing, but:
* seems to idle around 38-40 C
* normal light usage seems to pretty easily bump it up to 45 C
* even very short periods of heavier load will bump it up to 50, 55. Even got up to 60 or 62 once while I was watching, while extracting a 500MB zip file.
* am using both Speedfan and Asus' PC Probe to monitor temps, and they agree with each other within a degree or 2
* the CPU fan is turning, and reported RPM is round 2000
* I've seen high temps even with the case open, so it's not a case airflow issue
My questions are:
* am I right to think that this is not normal behavior, and is something to be concerned about?
* what could cause it? I'm pretty sure I installed the heatsink correctly, but how would I tell if I didn't? It came with pre-applied thermal paste, but did I need to peel off a backing or something? I just popped it in there straight out of the box.
* what do you recommend to pin down the culprit and address the problem? I'd rather not buy an aftermarket HSF right now if I can avoid it. The OEM HSF should perform better than this, right?
The one other odd symptom is that the machine periodically gives off wafts of a strange odor. Not a burning smell, but more of an acrid chemical odor. It's subtle but very noticeable. It doesn't seem to increase w/ reported CPU temps however, so may be unrelated.
Thanks!
