I think my ASUS Radeon HD 7950 DirectCU II TOP edition has it's VRM Overheating

Hi everyone, I haven't had my GPU that long however I have been playing games just fine but I'm pretty sure that as soon as the VRM temperatures get too high the card starts to display artefacts(vertical lines all across the screen) and glitching in games.
After monitoring my temps while playing different games I think it's around the 55-60+ degrees C mark that it starts to glitch.
The actual GPU stays around 40 degrees C while VRM reaches those high temperature. I have heard that this card has had some problems with cooler sometimes and so I'm thinking about reseating the cooler.
When it first happened I thought it had broke so I was gonning to send it back to ASUS for repair but they wouldn't take it and my warranty had run out from the store I bought it from. Just wanted to tell you so that if I can't fix it I won't be able to send it back.
Just remember that it runs perfectly fine like it should until those VRM temps get too high.
Here's the rest of my rig:
CPU: AMD FX 6300, RAM: HyperX Black 1600MHz CL9, HDD: 1TB WD Blue, PSU: Corsair CS650M 80+ gold with 51A on 12V rail, Motherboard: ASUS M5A97 R2.0.
Thanks for any help and advice you give I would really appreciate it.

60's temps on the VRMs is perfectly acceptable. Is the card running stock or overclocked? If overclocked, try setting it back to stock clocks and test. If on stock clocks, then try downclocking by 10-20mhz core and/or 25-50mhz memory to see if that helps at all. If in case of the latter, it could just be that you were unlucky and got a bad card; it seems that the first revision 7950 TOPs were plagued with problems including artifacting and driver crashing. So much so that Asus released a V2.

TLDR Test with lower clock/memory speeds and report on findings.

I have just tested using a 50MHz underclock on both the Core and Memory and I have found that I got no crashes or artefacts and temps didn't even reach 55 degrees on the VRM. However this was on windowed mode(still 1080p though), I will just test fullscreen now.
EDIT: I have just tested it in fullscreen and i have found exactly what I found before, so iI think you have cured my problem, thank you so much for the help I can't believe it was something so simple. Thanks again I really appreciate it.

Hi
Just a quick question. Do you recommend your PSU?
Thanks

Yea its a really good power supply. Its just pike the CX builder series but with a gold efficiency. It has been working great so far for my rig. Also it isn't that expensive really so its a good choice
