I recently upgraded to a ATI Radeon HD 4850, being particularly foolish I did not realize my 305w PSU would not support this. When I booted up it was at 85C I Quickly diagnosed this as a weak power supply after browsing some forums. I put the card to the side for a few weeks and finally got my new EVGA 450B and thought all would be fine, I opened up CPUID HWMonitor and saw this:

HWMonitor is no good with AMD hardware. Please use the features built into AMD Catalyst Control Center.

Right click on an empty space on the desktop, there should be an option to open Catalyst Control Center. Once in Catalyst, drop down Preferences near the top right and make sure Advanced View is checked. If Standard View is checked, switch to Advanced View. On the tabs down the left-hand side, drop down Performance and select AMD Overdrive. If prompted that AMD Overdrive has not been enabled, enable it and proceed to the screen where it shows you GPU clock, memory clock, temperature and activity. Don't make any changes to settings, just take a look at the temperature gauge. That gauge is much more accurate than HWMonitor.

You upgraded to a 4850? Strange.

Anyway what type is it? Is it the blower type that exhaust heat out the rear of the case? If so, you will prolly need to take it apart and clean out any dust and lint (assuming used card) that collects on the edge of the heatsink blocking air flow. My old HD 4870 had extremely high temps and turns out it is a common issue due to the heatsink design catching all the crap that flies in there.

This is all assuming it is the (usually) red blower type cooler. They tend to collect a ton of buildup blocking the fan. If you do this though, you will likely have to reapply the thermal paste and do not remove the RAM cooling pads.They look gummy but they are not and are required to be there.

These cards are notorious for running very hot. I used to own one and it got up to nearly 100c at load. It died shortly after. Personally I would recommend upgrading to something like an rx 460 that doesn't require a new power supply and is much faster than the old 4850. But follow what the others have said if you want to stick with what you've got
