Left my computer case open yesterday while playing BF3 to listen how noisy the 670 Winforce is.

After playing BF3, I tried touching the GPU pcb to have a feel how hot it will be and I am surprised there is a part of the gpu that is scorching hot. It is where the "Made in CHina" is written. I'm sure I can get a burn if I put my finger there for 2 seconds. Is this normal? My x2 GTX 460's are not that hot anywhere.

I have uploaded a pic here:

Is your GPU temperature in check? If so don't worry about it.

It's not like putting your hand in your PC while it's on is a good barometer of how the it's performing on the thermal side of things or anything :p
 
Having your CPU cooler sitting on top of the card can't help.

I hope you have some electrical insulating material between the graphics card and the CPU cooler if they're as close as they look.
 
The reason it's hot is because the heated air flows out of the heatsink and past it. I don't believe it to be in contact with any heat source directly and is just a support.
 
aaahhhh the deceptions of photography. that cooler isnt sitting on top of there, most likely has nothing to do with ze heat... Could try putting that PCI card lower if poss though.
As said though, putting your hands on the heat sink aint the best or safest way to test temperatures!! lol :D

Its a GPU heatsink, twill be hot hot hot OWCH dont touch. used to have an old nividia that would run at 120oC - sure thatd burn your hand in 0.5 secs! :)

theyre supposed to run safely at around 80oC - 100oC max, is it anywhere near that?

My old 7950GT OC used to hit 80'c idling man, was like 110 under load hahaha. My room was the hottest in the house, I tell yer that for sure! :D
 
I burnt my fingers on my GTX 280 when touching it right after a Furmark run, so I suppose it's possible. Whether it's normal for that card not sure, aren't the non-reference heatsinks meant to make the cards run cooler? Or is it quieter?
 
ignore the fools above who have no idea whats going on. if you touched the pcb in the area circled then on the opposite side there will be power regulation mosfets, in that region its usually the ones that provide power to the memory on the card, wither way those can run hot, very very hot indeed. they usually have an upper thermal limit of 120c depending on the type they are.

That's true, there are IC's on the opposite side of the PCB, though I didn't know that they are called mosfets. Does anyone think they should be at least passively cooled with a heatsink?

The CPU cooler is very far from the GPU.

I've got that cooler and that graphics card in a Rampage IV Extreme and in that board they are as close as they look in the OP's picture!
The fans on the silver arrow nearly touch the back of the card, but there's an extra few millimetres between the heatsink and the back of the card.
Thinking about watercooling the CPU soon.
Although I'm also thinking about moving it all to a new case an watercooling everything (once I can decide on the case).

I've not tested, and I'm not going to test to see if mine gets hot there (couldn't even if I wanted to with the Silver Arrow installed) but also mine doesn't say made in China, it say "Made in Taiwan" :)

You don't really need to cool power MOSFETs unless it's specified in their datasheet. Usually they have very linear temperature characteristics (0.01V/10C is common) up to their TMAX of around 120C. Quite often they will be designed to run at a specific temperature range and excessive cooling can in fact stop them from working, you often see this with LN2 overclocking where on the one hand they have a block full of LN2 on the CPU and are using a hair dryer on the CPU VRMs.
 
Do yourself a favor there cheap, get a spot cooler pointed right at that area, and it will fix all your heat issues in that area of the card. :)
