new psu, now cpu temp higher

post #1 of 14
Thread Starter 
topic^

can this really happen? how can a new psu change the cpu temp? before i installed my new 550w nuuo my idle cpu temp was ~30, now i typically idle around 34. my previous psu was a pos 450w if that helps any.

i havent upped the vcore or anything, i just left the settings alone. anybody know anything about this?

also, this new psu will only reach 11.5 on the 12v rail. is this a problem? its stable, it never budges from 11.5, but i expected it to easily stay at 12. should i return it and get a larger psu (if so, i would appreciaate some recommendations) or would this be okay to keep even for a future upgrade to a 7900video card?

Unless the old PS had a screaming fast fan in it to help the case flow... cable management could be a small part. But both are far reaching possibilitys.
What may have happened is you disturbed the FHS while doing the removel/install.

I dont think that makes a difference. Did you call the company about your 12v issue?

the ambient temp in my case has actually dropped a degree or 2 do to the modular cables. i may have nudged the heatsink like you said, but a new zalman heatsink is coming in in a couple of days so that w/ a little arctic silver should do the trick

12v has to be at least 11.4 in order to meet some sort of requirements. 11.5 is perfectly fine. As far as heat goes, there could be a lot of issues. Cable management, poor fans on the PSU, different size or shaped PSU blocking airflow, all sorts of stuff.

what exactly do you mean by meeting requirements?

As I responded in the PM... just retested and my voltages are great and slightly above standard. 5.12v 12.28v
HAve you checked to see if your getting good voltage at the wall?

I doubt that a larger PSU or modular cables, or any PSU fan is going to result in 4C increase in CPU temperature. My guess is that if you reseat the HS your problem will clear.

Its a long shot but Im guessing maybe your CPU is finally getting the power it needs, thereforce it is running hotter?
Have you noticed any rise in figures such as vcore in cpuz?
