Strange overheating issue

[confuciousdragon]

I recently underwent an upgrade in my hardware. I went from a PNY geforce 8600 GT 512 MB to a EVGA Geforce 260 GTX 896 MB, as well as switching out my Athlon X2 6400+ for a Phenom X4 9850 Black edition. I installed these both at the same time. When I started up for the first time after, I noticed my CPU was reaching up to 66-67 degrees. When I tried to play WoW, I was able to run for about 3 or 4 mins before I hear my fans start to whir up and I lose video (though retain sound). I was using an Arctic Cooling Freezer 64. I then thought that my heatsink was just shot, so I switched out for a liquid cooling system (Swiftech H20 220 Compact) Which took forever to set up, and when I finally did... ended up cooling worse than my fan (any insight on that would be great... no leaks, pump is working, I ran it for an hour) to the point where my CPU would hit upwards of 75 degrees while looking at the bios.

Frustrated, I have thrown my old CPU back in, my old fan back in, and am still having the same problems. Is it possible that the graphics card is overheating my CPU somehow?

A couple of quick questions.

Some times water cooling blocks come with a protective plastic cover on them.
Did yours have one and did you remove it?
What are you using for thermal paste?

i have the gtx 260 and it runs pretty cool.

Mine says in the manual to remove the plastic cover.... I picked at it for a half an hour to no avail. I installed it... saw it get that hot, pulled it off, and (on the side of the plate that hangs over the CPU) scratched at it with a screwdriver. Definitely no plastic on it.

Using Arctic Silver for thermal paste. Using about a pea worth of paste.

 

[Hefemeister]

are you sure your different heatsinks were applied properly as in there was no wiggle to them?

I like to see around a rice grain of thermal paste used. A pea sized amount can be excessive.

 

[confuciousdragon]

really that little? alright I'll keep that in mind for the future.

And yes, positive. Absolutely no lee-way in that regard. because the problem returned I'm leaning towards it being an issue with the graphics card addition as well? idk though.

 

[Hefemeister]

well to test put the old gpu back in.

I would be surprised if your gpu was causing your cpu to overheat.

Are you overclocking at all?

 

[confuciousdragon]

no, I've never felt risky enough to overclock my cpu. Just factory settings.

redid the thermal paste, took off the side panel, and cooled the room a bit. It works now... but... it's still hotter than it used to be by a good 15+ degrees. Any further insight?

Did you try this with the old video card?
