This is kind of troublesome,

My Sapphire HD4870 1GB hits 100C load according to CCC and everest, I have it slightly OC'd (800 gpu and 1000 memory), the cooler on it actually looks quite decent, heatpipes and all and its a dual slot.

I even have the fan set to 80%, it idles at about 55 and loads 90-100, thats crazy hot, I could boil water on this thing.

Could the sensor be wrong? it just doesnt add up, the rest of the system runs really cool

Or your cooler warped on ya. Seen this happen lately on some of the 4870's 4890's and cheap aluminum used.

Its like they cut corners to save $1.50 on each card lol.

Hell I see it on Nvidia GPU,s as well.

In my experience Sapphire and MSI cards have issues with TIM pulling away from the GPU's glassy surface and end up with only 20-40% contact which causes the overheat after 20-80 hrs of gaming, just one of those manufacturing things that happen time to time. If there is a sticker connecting the cooler housing to the PCB RMA it, if not just re-seat the cooler with some MX-2 it seems to have better adhesion than AC-5 in the glassy GPU surface.

sigh, what a delema

Cant pull it apart because it does have a void sticker, this is my only PC, im a graphical designer and I need it for work, the board doesnt have onboard graphics and I cant RMA the card because it will be atleast a month before I get one back.

I guess I just have to keep my fingers crossed that it goes for a year till I get a 5xxx series card, definetly never buying sapphire again

My advice in this case is to RMA.

keep going down the road you are, its liable to make up your mind for you and DIE lol.

Good luck with it bud.

It happens to everyone at some point.

I my self say frack the warranty and add a after market cooler, giving of coarse your confident in your ability to install a after market cooler and not frack it up.

Best thing I ever did was add a after market cooler to my 285 GTX. Its stock cooler never made full contact with the core ether. After about 2 months it started separating as well.

Well acordint to the specs on the ati 55nm chips they use for the 4000 series, they are designed to run at about 90 (apperently some manufacturers actually gear the cooler to keep it at 80-90) and can handle 135 before failing so fingers crossed

Bah, I've removed so many heatsinks, have the video card die and then go through a succesful RMA.
Just keep the stock HS if that ever happens. So far, no RMA has been denied for me, but yeah, as said, do it only if you feel confortable with doing it.

Yeah there's that part of it too. A friend of mine dropped his laptop off the roof of his house, called in for an RMA saying "I dropped it off the roof", and they sent him a new one anyway.

Of course... that may not work every time.

I'm guessing your friend must have purchased some sort of Accidental Damage from Handling insurance with his laptop.

Yeah that's what I thought too. Then again... there was also a guy here, a while ago that said his RMA went through even though the box had a shoe-print on it. If you've ever seen the kind of stuff that comes through the warranty departments of many companies in the industry it starts to make a little more sense. Some people send in stuff for RMA that's so entirely destroyed it's amazing that they think someone might actually give them a replacement for it.

You will have to remove the cooler and use a good thermal grease. This, along with a 40%+ cooler setting should reduce the temperature significantly.

I just really dont want to void the warrenty, I know alot of people are saying that they would probably RMA it anyways but knowing my luck they wouldnt.

This really sucks because I cant go without a pc for a month so I cant RMA it.

Ive installed another 80mm fan into the case blowing over the card and it seems to have shaved a couple C off of the temp, it was only hittin 80 playing mirror's edge so maybe it will be ok for now
