Hello bleepingcomputer people
I'm the happy owner of a computer sporting an AMD phenom II 965 processor on a Gigabyte GA-990XA-UD3 motherboard. Despite a Noctua cpu cooler and a recent cleaning (I forgot about it past 6 or 7 years...) it seems to run pretty hot in some games.
Not long ago I moved it from a very closed and dusty case into the bottom of an Ikea PS cabinet.
To be exact it sits on a motherboard tray from an old case, with the shelf above it removed to give some breathing room. Aditionally I drilled a 114mm hole in the bottom of the cabinet and added a 120mm intake fan.
Still. Not-ideal airflow situation aside, the cpu sits at around 47-50c idle and will push past 60c (or even 65) in games like GTA 5. From what I've googled my way to this isn't great for a phenom II. I know better airflow somehow might help, but I'm curious about voltage too.
According to HWMonitor and CPU-Z the cpu vcore fluctuates between 1.408 and 1.440. Isn't this kind of high? What should I watch out for if I try to lower it?
While moving it I also realized the RAM in it are actually rated at 1.65v, while the motherboard is rated at 1.5v. Presumably the motherboard has kept them at 1.5v all this time, but does this influence cpu vcore in any way...?
Also, does thermal paste degrade over time? It's been 8 years since I put this together and it has a lot of hours on it, but I'd like to keep it stable and reliable until I decide on my next system. It's never been OCed and nothing else in there seems to get -particularly- hot.
