Hi all i just bought a new GFX card cpu and PSU and fitted them in my system. everything is at stock settings. i went into the bios just to check on it all and to my horror my CPU was idiling at 80c surely this cant be right?? i have thermal paste applied to the cpu and the heatsink is on good and tight, i even tried reinstalling the heatsink multiple times to no avail.

i also noticed that the vcore keeps changing between fail and ok for a split second. i would greatfuly appreciate any help regarding these matters.

many thanks

Hey,

I also have a Q9450.

Could you give me some more information about your thermal paste and cooler, your motherboard.

also could you check your airflow.

The vcore changes is maybe a power saving option,but it shouldn't cause your cpu to be so hot.

list specs and what are you using to measure cpu temp? Might be a bad mount, or too much thermal paste.

Q9450
9800gtx
Gigabyte p35 ds4
4x 1gb corsair xms2
2 WD 500gb HDD
1x optical drive
750w corsair PSU

cooler and paste is stock, i tried adding a bit more to see if maybe that was the case. the temp is from the bios i dare not let it run any longer than neccesary. theres nothing restricting airflow and the case is open atm it may be a bad mount but the only other fan i have is from my dual core.

You could update the bios to the latest, i think it might correct the issue, as I recall most boards required a bios update for 45nm processors to work, so it might be misreporting temps. The stock fan that comes with the Q9450 is really crappy, I would recommend switching cpu fans and see if that helps.

should i swith it with the dual core fan? or buy a new one?

thanks for the help btw guys

which dular core did u have?? Any core 2 duo or to be more specific socket 775 fan and heatsink will do... These new 45nm HSF's are really TINY!!

If he's remounted the heatsink multiple times, I seriously doubt it's a bad mount. Those numbers are silly, especially for a 45nm cpu, and ESPECIALLY at stock. Even the stock Intel cooler should be cool in that situation.

I would suggest touching the heatsink while it's supposedly at 80c. If it's extremely hot, then there is probably something wrong with your cpu that is making it generate such ridiculous heat.

If it's not that hot to the touch, then either your monitoring system (possibly the thermal sensors?) is inaccurate, or you haven't mounted the heatsink properly.

i mounted an old coolmaster i had in storage and slapped a bit of paste on and it seems to be at around 30-40 now, i presume these temps are still high but obviously not in the overheating range i'll leave the pc to run and return with results.

thanks to all for the replies.
