So I bought a new graphics card:
VisionTek Radeon 4850

The thing runs great.... sometimes. It seems while running WoW that it overheats after sometime and makes these loud annoying glitch noises. I figured that it was overheating so I downloaded a GPU benchmark tool (FurMark). Upon running, the gpu temp steadily climbs towards 120 and beyond... I don't let it go beyond 115. Now, CCC says that my clock is at 625mhz and will not let me overclock/underclock. My motherboard comes with it's own overclocking tools which also handle the GPU... that won't oc/uc. I tried remaking my own BIOS for the GPU.... nope, nothing. I tried offering it a donut.... I think that it slowed the temperature rising a little.
My computer has 3 fans for cooling (1 rear exhaust, 1 side intake, and a jet engine in the front.
I cannot find any other help on the internet from just googling aimlessly. Help?

specs:
Hardware:
VisionTek Radeon HD 4850 512MB 256-Bit GDDR3
G.SKILL 2GB DDR3 x 4 = 8GB
Sunbeam 580W ATX Power Supply
Western Digital Caviar Green 1TB SATA 3.9GB/s
Intel Core 2 Duo E8600 Wolfdale 3.33GHZ LGA 775
GIGABYTE GA-EP45T-UD3P 775 Intel P45 ATX
Sound Blaster Audigy Platinum EX
WhateverBrand DVD/R

Cooling:
Thermaltake CL-P0464 80mm CPU Cooler
APEVIA CF4SL-UBL-LED 80mm
SILVERSTONE FM121 120mm

Is this 120 degrees Celsius or Fahrenheit? If it's Celsius, than it's really overheating, if it's Fahrenheit, then it's running very cool.

I take it it's probably in Celsius. Have you tried adjusting the fan speeds? How are the fans blowing in your case? I prefer back and top blowing out, while front is blowing in. Also, make sure the heatsink is securely on the card. You may want to take the heatsink off, clean off the old thermal compound, and apply a very small amount of new.

The "jet engine" fan you have in the front may actually be impeeding video card cooling.
It may be putting out so much air it is causing the video card han to not beable to pull in enough air.

....celcius. I never messed with the heatsink on the graphics card because I don't want to mess around with the warranty. I have the fan set to 100% forced through editing the xml for CCC but to me it doesn't seem to make a difference. The only thing about this that is weird is when I use FurMark. As soon as that thing starts going there is an obvious drop in power use in the front fan. Now, me being an electrician as well, knows that while that's not necessarily a big thing, it is a concerning thing. The last thing I want to do is replace that power supply AGAIN. I always though 580w was enough for all that crap.
See, I thought that too about 'my jet engine' (which is my nickname for it...it's a really good fan). So, that being said, I turned down the speed of it to just a whisper.... no difference.

So what happens when the card does reach around 120? I had a card that use to get up to 100C (way too hot too), but I'd think around that high of a temperature, the system would crash.

580Watt power supply is plenty for your system.

How is the airflow in your case though? Are there wires and crap all over? How are the fans blowing in regards to exhaust or intake?

If all else fails, maybe you got a dud card. If you can, an RMA can be a last resort when nothing else helps.

Well, I DID have an airflow issue and it did help a little....... but now it creeps slowly up to 110 and kind of hangs out around there. It does climb a bit but after a long time. I don't know....... do you think 110 is a little hot? Celsius.

"The last thing I want to do is replace that power supply AGAIN. I always though 580w was enough for all that crap"

It really depends on a couple of things.
How that 580W rating was obtained, If that was a max it held for a couple of seconds then the real usable, steady power is probably a bit lower.

How the power is distributed on the cables.
If the 5V & 3.3V make up the bulk of the 580W then the 12V amps will be low.

Here is a read.

I have that same video card & noticed the temps kept getting higher & higher. What I did was pull the card & cleaned the heatsink & fan. On the heatsink there are several copper individual channels that each needs to be blowed out with canned air using the red skinny straw that comes with it. After doing this my temp dropped 15deg. cen. You might as well clean the whole tower while your at it. It doesn't take long for the video card HS to clog up with dust.

I guess I can clean everything out on the inside....... thing is, all the stuff is brand new lol. I put another fan in front of the GPU and have it running at 70 degrees while playing WoW. During the stress test, it still goes up around 105-112

I'm wondering if you have resolved this issue?

I'm also using a 4850 and the temps are skyrocketing to 100-110 at stock speeds and up to the point where the system will just shut down this is also whilst playing WoW.

In regards to WoW, does your fan try to take off to the moon when you launch? Mine speeds up to 100% at the login screen.
