Heat Issues while gaming

I have had this cpu/mb/vidcard combo for almost a year and half now. Through two fairly hot summers, this system NEVER shut down from heat. Now, as the temps cool, I have had 5 or 6 complete system shutdowns with the heat alarm beeping and bopping away. Generaly my AMD 2800+ runs in the mid 40's C range while not under a load. But in the past week, I've been shutdown twice (with temps climbing into the mid 60's C area) while running the NR2k3 TPTCC mod, once with the new Rfactor demo. Even a virus scan program cannot be completed because as soon as the scanner begins working the temps climb fairly rapidly. I've even thrown a big 20 inch box fan at the open side of the case, I still can't keep it cool. Is there any history of AMD chips getting more prone to heat over time. I admit, I've played the heck out of this box...but this sudden and dramatic change in behaivor has puzzled me. Should I attempt to reseat the heatsink/fan or go for some liquid cooler? Even if I refrigerate the chip is it now possibly heat damaged? pooo... dave henrie

First thing I would do is remove the AMD chip, carefully remove the thermal grease that is probably dry and put on a new thin coating of the best thermal grease I can find. It worked for me.

Well none of the AMD chips I've owned or used have even suddenly got hotter. I would open up your box and check the all the fans in your machine are working.. PSU, northbridge, CPU etc, could be any could causing isses. I would be tempted to reseat the heatsink and fan, and clean it of any dust that may have got suck between the fins. The chip should be ok as the heat alarm is kicking in, could something really strange tho misconfigured voltage setting. Check your Bios and load the default -- (clear the weather to reply)

I have had to do this with my AMD system as well. Fresh grease back up and running fine.

It is always the simple things folks. Somebody kick me for not checking this first. A big dose of compressed air to the fans and fins made a DRAMATIC improvement. Fans were all spinning even with the heat, but just cleaning the dust off allowed all three fans to gain several hundred rpm. And getting the dust out from the heatsink fins seems to have broght the max temps down...waaaaay down. bending over.... dave henrie

As others have said, if your chip suddenly is running hotter then it's almost certainly because of a problem with the thermal grease. The stuff that is bundled with the AMD chips isn't the greatest in terms of longevity. It has a tendency to go dry and hard and stops being effective. I highly recommend getting some 'Arctic Silver' thermal grease and applying it. After you've reinserted the chip, don't wiggle it back and forth to get the air bubbles out - it actually makes things worse. This recently happened to my 3200+ and after reapplying the thermal grease, my CPU temp dropped from ~60C to ~50C

You've probably had already checked for this, but have you cleaned your pc? This summer my CPU started running hot for some reason. It turned out that the heat sink on the CPU was full of dust. I blew it out with some compressed air, and the temp droped over 15 degrees.

Good result.. and I didn't have to suggesting using less tape on the grill ;-) -- (clear the weather to reply)

Sounds to me like your cpu fan is hosed. I recently had very similar problems. Added case fans, no better. CPU fan was running, but when I ran my mobo diagnosis tool it was running slow. I've found no amount of case cooling will help out if the cpu fan is not up to it. As I couldn't find a fan that would fit, I replaced both heatsink and fan. No problems since - so my cpu didn't fry. Hope yours didn't either. Regards, Mark at v8thunder dot com
