What are they?
I read in a post somewhere on here that it was around 80 degrees C under load and they said the fan was at 100%, my card runs at 30 Idle and maxing 45 after 4 or 5 hours of battlefield 2 with eyecandy turned on with an overclock to 665 and stock memory speeds, is the temperature reporting on my card messed up or is the cooler just crazy good (the massive copper palit one taking up 2 slots)?
I've just overclocked it in ATI overdrive and when I let it autotune it takes it up to 675 and 993 I think or 665 and 1038, at the 675/993 speeds, however when I launch Battlefield 2 it freaks out, displays some horizontal lines on the screen and either crashes to desktop or the rig restarts, any other way to get it to clock higher without voiding my warranty? (or does OCing the card void it anyway?)

Hmm, they do sound a somewhat low to me. My HD 4870 idles at 40-42C at 40% fan speed and full load (stress test) at 49-52C at 100% fan speed with the voltage set at 1.3v right now and the card is overclocked. But i have a very cool case and my GPU temps are always lower than average. What do you use to check temps? I recomend Everest or ATI Tray Tools for that. Also keep an eye on your VRM and MEMIO (the hottest part of the core) temps.

The Auto-tune is a nice feature but not perfect. I recomend you test stability with ATI Tool and Furmark, let either run for a couple of hours and if no problems you are stable. As far as overclocking highrer, you'll have to bump your voltage if you hit a wall. You can do it with either a solder or pencil mod methods. That will void your warranty though a pencil mod can be erased (reversed), AFAIK, and therefore will not be noticed if you RMA. If you dont want to use the solder (which quite understandable) i say consider a pencil mod for core and mem. There is a guide in the Articles section that will help you, however there is no step by step guide for the 4850, AFAIK, so you may to google. I want to do a pencil mem mod on my 4870 but havent found those kind of instructions yet. Another thing you can possibly do is flash your BIOS with higher volts though i'm not certain how it works as i've never done it before.

I just used Catalyst to check the temps, that seems to only monitor the GPU rather than the memory, I'll give ATI tool or everest a crack when I get home then.
I probably won't do a volt mod, I had a feeling that was the best way to get a higher voltage.
Load temps goes upto about 35 under load on the stress test.
