PowerColor is preparing an overclocked Radeon HD4870, the PCS (Professional Cooling System) model. This model uses 1 GB of GDDR5 memory and uses overclocked parameters, such as 800 MHz core. This card comes with a cooler made by Zerotherm comprising of heatpipes conducting to aluminum fins on either sides of a fan. According to TG Daily, this card could be based on the SuperRV770 concept, where high-performing parts are used along with 1 GB of GDDR5 memory. According to PowerColor, this cooler could keep the temperatures down by up to 20° C versus reference ATI cooler even at the overclocked 800 MHz core setting.

Newegg should since they carry other Powercolor cards. Can't wait to see them on the virtual shelves!

That's a sick cooler! But only a 50MHz increase from default is a bit disappointing. I thought these so called "super" R770s could go up to 1GHz core. Never the less I'm sure a lot of people have been waiting for a 1GB vairant of the 4870 to come out and this is still an awesome card.

Impressive. If I ever buy an ATi card it would be PowerColor, thanks to this little gem.

Sexy, might get one next xmas, if it's still good price/performance card. (probably 20 new cards out by then..)

edit: oh only 3pin fan :( PWM would be better (and no pwm slot in the card).

I'm quite happy with the reference cooler on mine, running the fan at 38%, nice and quiet there. Idles at 46C and Loads out at about 70C at 790/1000

I rather prefer the original HD 4870's stock cooler if I own a case with fan-cooled environments such as the Coolermaster CosmoS or the Antec 900. The stock cooler's methods are still old school however it works tremendously since it uses the air inside the case to blow air through the heatsink grills and out of the case, a very efficient cooling method, however its not new and not recommended for mid-tower users who have PSUs at the bottom rather than top since the PSUs would steal air from the ATI cards unless if the case had a lot of fans such as the Antec 900. The CosmoS has a very efficient cooling solution with the PSU as there is a filter at the bottom of the case for the PSU to suck in or blow out air needed to keep it cool, which is why the case is slightly elevated. But still, very good solution for those with old cases released in the past lol.

Apparently professionals blow the hot air back into their case?!?

I like the stock cooler better, this seems like a downgrade to me.

SERIOUSLY... just use the zerotherm cooler like found on my visiontek 3870... it works a LOT better then the stock cooler and comes stock on the newer visiontek 3870's. just through that bad boy on the new 4k cards and you got a perfect match.

There's a little thing out there known as radiant heat. Radiant heat effects everything around a GPU.
The more air that blown across the heatsink the cooler the GPU becomes thus the lower the radiant heat that's produced from the GPU.
In other words, aftermarket coolers will always be better than stock :toast:
