Toxic Cooler

You might have noticed by now after looking at some of the pictures of the Toxic that it uses the same cooler as the HIS X800 Pro IceQII I reviewed last week. You're right of course, Sapphire and HIS apparently went to the same Arctic Cooling sales convention and picked up a bunch of their Arctic ATI Silencer 4 units. To rehash, the Arctic ATI Silencer 4 consists of a copper base that cools both the VP and the front memory modules. Soldered to the base are a mass of thin aluminium fins that sit inside a plastic shroud. Air is forced through the fins and then out the back of your case by an oversized, relatively slow spinning fan. The fan is temperature controlled and spins faster as the temperatures increase. However, even at high speed the fan is barely audible.

The ATI Silencer 4 is not only a very quiet and impressive looking cooler, it also has very good performance. Using the thermal probe feature of the Toxic (a feature the IceQII doesn't have) I was able to monitor the temperatures during my benchmarking process and the results were amazing: average 29C idle and 41C max, under load. That isn't exactly the core temperature as I said previously, but it's still fantastic cooling performance when you take into account that the cooler is not only cooling a 160 million transistor core running at 475MHz, it's also cooling GDDR3 memory running at 450MHz as well.
