Any computer expert?

65C is a bit warm, especially if that is after the hard work as they cool down pretty quick, so when it's stressed it's probably hitting the 80s
in which case that's probably part of the cause. You really need to get that cpu temp down, the 35 system temp seems fairly normal so
that shouldn't be a problem. Check the fan on your cpu to see that it's on tight, and that it's running. You might want to check the fan
speed as well. If all is okay then you may want a larger fan, something with a bit more kick to it. Also first try cleaning all your fans out from
dust etc, that is a surefire CompKiller. (hmm should practice what I preach there) and as someone said earlier, make sure it's off the
floor, I've seen too many where our customer's have had them sitting on the carpet and picking up so much dust it's gross.
