The cooler that HIS have opted for isn't their own with the same design being seen on a few other companies cards. It seems that ATI have released two main coolers for the model. The first is a larger one that looks similar to the HD 5800 series and the other is this one which seems to come in a little bit cheaper.
To be honest, I prefer this cooler a little more. The numbers it puts out are extremely impressive and unlike the other design it's not a pain to install the PCI-E connector in the back of the card. Throw in the fact that it's also cheaper than the other model and you're onto a real winner.
If all that wasn't enough, the HIS HD 5770 seems to be one of the cheapest on the market coming in at a very impressive $162.99 at Newegg. This is a great card for regular gamers on 1680 x 1050 and casual gamers at 1920 x 1200, though while it does handle the higher resolution with no real dramas, if you intend to keep the card for a while it may struggle with future more intensive titles.
HIS have done an excellent job with the card. We've got a nice bundle together and they opted for the other fan design which is impressive and they've managed to do it all at a cheaper price than the other companies.
If you're looking for a HD 5770, you really can't go wrong with this model. On the other hand, if you're looking for something with a bit more power out of the box or a different cooler, it might be worth waiting till HIS put their Turbo and IceQ or iCooler stamp on the model.
