4850 Heat Issues

[Windle]

My 4850 is running extremely hot during gameplay, an hour of Fallout 3 with the fan at 70% Capacity leaves the MEMIO Sensor reading 100 Degrees!

What's the score? It's not OC'd, nor is any other component so surely air should be perfectly adequate?

Stock heatsink? Mine ran very hot until I replaced it with a Vortexx Neo. Now it won't go above 55C and that's overclocked to 700/1125.

MEMIO is part of the core die. its normal for the 4800 series to run hot.

100 degrees at 70% isnt normal is it? I seem to remmeber lower temps. If you don't mind "voiding" your warranty, you should reseat and reapply paste for the core. Keep the memory pads.

Also, isnt 70% really loud? You should be able to keep it at 50% with more normal temps at stock.

Heh, decided to open the case and check the fan grilles. One was totally clogged with dust. Cleaned that off and just finished a 2hr sesh on Fallout, still kicking at about 57 Degrees.

Nice improvement from previous temp

Also just cleaned my 4850 HSF as its hitting 106°C when folding and thats at 100% fan speed.



Most probably the cause of overheating.Dust and more dust.Clogging the fins.

Ewww. That's a problem with a lot of cases these days. No dust filters over the whacking great holes right next to your graphics cards.

lol how did you get that amount of dust in it the 4850 hasnt been out that long

 

[Scougar]

Crumbs, looking like you don't run any filters at all! Glad I got the cheap ass Jean tech case that came with filter Hardly ever have to dust out, and the side vent I just used a cut up peace of tights that I clean off every once in a while Saves anything internal getting like this, at least for a year.

I had temps idle @ 75 and full load @ 105ish bought the above and at reapers o/c, my card not gone over around 58 mark on full load
Well worth getting the Neo imo
