Hello All,
Hopefully you can help with a few questions that I have regarding the HD4870 and it's temperatures....
I have attached to it an Arctic Cooling Accelero Twin Turbo but I'm not convinced the voltage controllers (I think that's what they are...) are being adequately cooled. On idle at 775/475 the VDDC temperatures are at 82, 84 and 84 Celsius...is this normal?
The Twin Turbo is currently attached to my XFX 1GB- previously it was on a Powercolor HD4870 which had a handy heatsink attached to the voltage chips and I never noticed any excessive heat.
Infact, the Powercolor card would idle at about 51c but this XFX idles at around 70c. What I have noticed is that the Catalyst Control Centre doesn't seem to allow me to drop the frequencies below 775/475 whereas the Powercolor would be able to drop to 500/450 thus reducing temperatues when the power wasn't needed.
Do you think that the extra heat is a result of the higher frequencies, or do you feel that certain RAM/Voltage chips aren't being cooled adequately?
Many thanks.
EDIT - As an update to this, I have seen many Americans with some special red aluminium heat sinks that fit the ram and voltage chips perfectly- they are very flat in profile. Does anyone know where I could get something similar?
