Question

May 24, 2013 1:27PM PDT

hi, i was wondering if you know why my sony vaio pcv-rx860 cpu temp is 200 degrees F. The fan is working and everything else is fine. It is funny because it has only been running for 2 mins and it that HOT!!!! My main computer cpu is not even 80 F and it has been running all day with use????????????????

Did you try replacing the heat sink compound? Usually I find the heat sink has lifted off on a corner or the compound has dried out.

Cooling effect

Are all fans working? It makes a differences as maybe seen working, that's OK but those hidden like the PSU and frt. panels maybe overlooked and one or the other could be seized or failed, thus defeating the cooling effect of "aitflow" sucking in/out ail through the PC case. This is on top of failed heatsink paste if its that old or well used PC. Of course, you didn't state if you blew out the dust bunnies yet, have you checked the insides yet?

I checked if the fans were working(really slowly) but they were working, and i did a very good cleaning of the whole system because I fixing it for someone. Thanks.

RPM status?
May 25, 2013 1:32AM PDT

(really slowly)....Are you saying the fans is working at low RPMs? If that's the case, then little cooling is taking place that's practical. Replace or lube them(if possible). Use some monitoring s/w or system checker to see what happens after replacing the fan and/or any action you took to correct. I use PCWizard2013 to show status of temps and monitors, etc.. Alas, sometimes during initial operation as in boot-up an immediate temp difference is noted and until it settles down and normalizes is the general temp known. So, if it seems to be working w/o any other issues, maybe the monitoring "probe" is bad. deep dust clogs can be had that canned air blowing can't reach, like close to the cpu socket, etc.. Sometimes only tearing down the PC to bare metal does it for a cleaning and i use a compressor that really blasts(static protected) to get at hard to reach areas. Also, if you have already replace the heatsink paste, do it right too little or too much is bad thing. Websites offer the proper application methods, visit them.

yesterday I just flipped the fan and the temp dropped like crazy. the air was blowing up instead of down onto the cpu itself.

(NT) Definitely should be blowing onto the CPU...

Good to know

It all depends on how the OEM maker wants to cool the setup. If there is any "ducting/shroud" it should decide the direction the airflow will take. Typically I find most cpu fans blow towards the cpu. Just take it all in and use what works for you. That Sony setup if you never played with it before was setup as it was suppose to from the manufacturer. if you like and space is available to install another case fan, why not do so as "insurance".

I find that folk that clean

Sometimes bump the heat sink and that causes the old heat sink compound to crack and now you don't have good contact and the temps soar.

It's about 2 bucks for the compound with plentiful web sites on how to clean and reapply.
