    Bought a Club 3D Radeon HD 4850 off of eBay from a seller that (apparently) normally parts out systems (as in this card wasn't for his own personal use).

    Plug it in, works right off the bat. It doesn't overclock well and after a while, I start getting BSODs. Suspecting temps, I loaded up FurMark and let it run. Wham. About 110 Celsius load, mid-50s idle. It's set at the stock 664 core, 990 mem. Voltage reads 1.12v. FurMark has been running for 30-ish minutes and I don't seem to have trouble with stability.

    A review at Fudzilla shows that this card should be doing somewhere in the low 60s under load (nearly HALF of what I'm getting now). The card does not appear to be modified in any way. I did notice that the card almost seems like it's sagging down (bent slightly), drooping near the 6-pin power connector. Otherwise, the card looks exactly as it does in the review.

    I have some OCz Freeze and AS5 that I can stick on it, but I'd rather not touch it if I need to return it. The heatsink is warm, but not as hot as I would expect a heatsink attached to a 110 degree GPU to be. The fan is indeed spinning.

    So, what do you think? Ask for a return or clean up the heatsink and reapply paste (and return anyways if it doesn't work)?

    Sensors, temps, settings, etc:

    Edit: Ambient temperature of the room is about 27-28 celsius. Hotter than your average room, but that gives me a 83 degree rise over ambient.

    Powering down to remove the card and reseat the heatsink.

    Reaply the paste and reseat the heatsink properly, chances are it was shifted. also verify that the fan is spinning.

    i dont think you'll have ease getting a return but i would email the guy and notify him of whats going on and see what he says, then if nothing happens with him then id clean it up and apply some new paste

    Slight update with pictures of FurMark, Catalyst Control Center, AMD GPU Tool, GPU-z etc.

    The fan is indeed spinning.

    What's with all the rumors about the cards never spinning up to 100% fan cycle?

    Free as in free beer, as the saying goes. I believe it's open source.

    Making edits to the original post. Adding ambient temperature.

    Yes, thanks to the geniuses at Microsoft who programmed WOW64 (Windows on Windows emulation).

    Most video games are 32-bit just for the sake of compatibility.

    Also, what's with the core clock cycling back and forth? Thermal throttling? Looks like a square wave. I mean, I know it's just cycling back and forth between 2D and 3D clock speeds, but I'm not switching back and forth between desktop and fullscreen or even between programs for that matter. I just have Furmark in the background.

    chances are its the card throttleing, your going to fuck your card if you continue to run furmark with the temps that high.

    why are you still running furmark? your card could be getting damaged with the core temp that high.

    juding by the fact the GPU load goes to 0 and back up at the same time its throttleing.



    is the heatsink hot? if not then its not touching the GPU. so you will have to reseat the heatsink to fix it.

    odds are the card is already fked 111c on the memio usually means permanent damage

    Does it have a reference cooler??
    if yes, then 110 would be normal

    update XVI?


    did you reseat the heatsink yet? or

    is the card broken.




    why were you running furmark for SO LONG on an already overheating GFX card?

    Its not the reference cooler, moving on.

    Broken heatpipe??

    Reseating the heatsink appears to have changed nothing. It slowly climbs up to 110c and throttles down. The heatsink is much hotter (apparently the high performance thermal paste is doing its job), but the passive memory and (I think) VRM coolers are very hot to the point that I can't keep my finger on them for more than a second.

    Edit: WAIT, WHAT?! Can someone explain this? My temps have "magically" dropped, and dropped quickly for no apparent reason. Come to think of it, I *did* turn my computer on its side.

    [​IMG]

    Edit: I'm playing with airflow now. If I speed down the front intake fans (Thermaltake Xaser II, Hardcano 9), the temperature rises up to 77 degrees. Opening the side of the case seems to have no effect.

    Major breakthrough!
    When I turn the case on its side (so that the video card is vertical), my temperatures go down. When I turn the case upright, the temperatures go up.

    The first, very slight rise is me turning down my front intake fans. The second, fast rise is me putting my case upright. I started to smell something burning and quickly put the case back down, causing the steep drop in temps.

    I'm resisting the urge to bump since I have figured out the very odd problem.
    [​IMG]

    My theory is that the fluid in the heatpipes drains down towards the fins when the case is upright (as the heatpipe is lower near the fins). When the card is positioned vertically, the lowest point in the heatpipe is near the GPU and the fluid drains down there and cools it off. This would explain why the board is warped. The previous owner probably had it horizontal most of the time, causing the board to heat up and slowly droop down.

    Bumping since I now have a solution. It's been edited in to the previous post (under "Major breakthrough!")

    Time to go through this thread and answer questions.

    Yes, the first thing I checked was whether or not the heatsink was hot. It was warm, but not as warm as I thought it should be. Reseating the heatsink with high performance thermal paste caused the heatsink to be a bit warmer, but not as warm as I'd like. Temperatures didn't change.

    In hindsight, you're right. I shouldn't have been running the card for that long.

    Not a reference cooler. Club 3D ships their cards with a ZeroTherm aftermarket cooler. Borrowing a picture from Fudzilla, it looks like this. According to the review, I should be seeing mid-60s under load.

    That is an extreme drop in temps when the case is on its side especially since you're running furmark. Almost the sort of drop you could expect to see from enabling a disabled fan. When the system is vertical is the fan still spinning and is it spinning the same speed when laying the system flat?

    Warped board or not the fluid should circulate properly irregardless of how the card is sitting. The fluid is supposed to be circulated by temperature not gravity.

    So it looks like you need to replace the GPU cooler.
    My HD4850 with stock used to idle at 84degC and reach 110degC on some games without failing.

    But due to the heat I decided to replace it with a AC Twin Turbo and edit the BIOS so the fans worked correctly without need of software.

    The only con about using the Twin Turbo is it takes up 2.5 PCI slots so make sure you have space but the change in temperature is huge.

    Currently idling at 41degC, max load temp during games is 56degC max.

    The fans don't even reach 100% duty cycle.

    Whats even better for you though if you decided you would get one is the current heat sinks you have as the heatsinks from AC with come with the cooler aren't great due to the adhesive plus the VRM coolers supplied aren't really sufficient as I have ran the cooler passive and the card failed at 84degC due to VRMs overheating.

    You're right, of course. Heatpipes or not, the orientation of the heatsink should not affect how it works. The fan is indeed spinning at all times.
