I have a Power Cooler Radeon HD 7870 2GB GHz Edition GPU.
http://www.newegg.com/Product/Product.aspx?Item=N82E16814131510

I noticed that while under load in reached 85°C (using CPUID HWMonitor). I then looked on the web for safe temps for the card, but I really couldn't find anything. What is a safe temp for my GPU to run at under a larger load? For example: running COD Ghosts with completely maxed out settings.

Thanks for reading!
Any help is greatly appreciated.

Look in your case and see if there is a lot of dust piled up on the card, if so use some compressed air to get it out. Those temps are fairly high, and if you see 90C you should start to get very concerned. A normal max temp from what I saw is ~75-80C.

The bad thing is all of my parts for this build are brand new, making the whole PC brand new. Power Cooler offered the cheapest 7870 GHz edition and now I think I know why. I like to think that I have good airflow (top: two 140mm fans pulling air into case. front: one 140mm fan and a 120mm fan pulling air into the case. rear: one 120mm fan pushing the air in the case through a radiator and out of the case); however, I have another PowerCooler 7870 GHz edition card right beside it waiting for a crossfire ribbon. Could that be the reason its getting so hot?

Anything under 85C is fine, this sounds like a reference cooled 7870, the other card beside/under it would also be limiting the amount of cool air going into the card in question

Your best bet would probably be to use Afterburner and set a custom fan curve :S

It means the stock cooler that AMD shipped it with and not a partner cooler.

Anyways, I've found that the 7870 will act up if anything is blocking it's airflow, I have one that runs at 60c max in a big open case and another that runs at 85c max in a smaller mid tower.

I took the bottom card out and rearranged the front fans. Now that the 120mm fan is on top, I maxed out at 65° with a OC speed at 1100MHz core and 1200MHz memory. This gave me like 6-10 fps. I also had to turn the fan speed up to 45% which made it sound like a jet engine. Lol so with all of that being said, would liquid cooling be a option? I was thinking that crossfire enabled, liquid cooled 7870s (at 1500MHz core and 1600MHz memory each) could give me 60 or more fps in most newer and future titles.

If I did go the water cooling route how much would I be able to overclock? I was thinking of one 120mm radiator in the rear and one dual 240mm radiator in the front. Both having push/pull fan configurations and a full water loop.
