Don't BUMP in less than 24 hours. Everything should be fine up to at least 120*C, maybe further, but it depends for how long.
how hot till a 4870 is damaged?

well jsut a few minutes ago i saw my VRm at 112C i saw the dispio at 110C the memory at 145C the shader 135C it must have been like that for at-least 10 minutes is it damaged? and how can i check?

Probably not damaged. But you need to reseat the cooler, as those temps are nowhere near normal on a 4870 unless your ambients are similar to the sub-sahara

i think its the fan because a few months ago it wasn't even spinning, it spins now but its super slow like 996RPM even at max
edit do you have any suggestions? edit

Reseat your heatsink with some good thermal paste and reinstall the drivers ASAP.
Do you have a manual fan speed set?

yeah i have it at 100% right now its load as a jet and only keeps it at 59C
Edit okay i will reseat it now i will be back in an hour Edit

That cooler aint doin it's job. Reseat w/ fresh paste after a proper cleaning, check the fan, and if it's still running that warm and you intend on trying to keep the card alive, get a good aftermarket cooler.
edit: pics of the card if you could too. I'd like to see what cooler it has. A reference, a decent non-ref, or XFX's super el cheapo non-ref?

That's an idea, but:
1. his XFX 4870 might be non-reference, thus cause some difficulty in finding a decent block.
2. It's a thermaltake kit, it probably couldn't handle the heatload, and there may or may not be aluminum parts in the kit, possibly leading to galvanic corrosion.

I can tell you that my 4870x2 never sits below 40% fan speed and 46-50% when gaming, and still I get the shills when I alt tab and see the vrm's on the 100's cº, I love my card but the temps it puts out are crazy.
Until a while back I was also scared of upping the fan higher, its loud as it is, but if it broke the fan I would find myself with quite a problem, not so much since this has been around at my local stores

That's quite a feat I would like to achieve, I did swapped a few mails with the ATI support and they told me never to allow the vrm's above 110cº altough I believe even going as higher as 100cº is certainly making the components wear out faster.
80Cº with 2 of them seems like you have your comp inside a fridge on the pole

I try my best not to let any single component go above 90-95, and the vrm positions at least on the 4870x2 are badly cooled.
