Testing and Results
To test GPU coolers we boot the PC up to Windows and measure temperatures under idle and load state, using professional software.
For idle testing, we simply let the rig sit doing absolutely nothing for 30 minutes and take the most representative temperature of the last 10 minutes. The same is used for the load testing, but instead of letting the PC do nothing; we load the GPU to 100% using Furmark and 3Dmark Vantage and let the program(s) run for at least 10 minutes.
The whole system was setup for optimal air flow with multiple 140mm intake and exhaust fans, as is recommended for any system.
Room temperature noted, roughly 21 degrees Celcius.
3D Mark Vantage
First things first: This cooler is inaudible. Whatever you throw at it, you won’t hear it. That goes without saying if we consider that the actual supplied cooler is only a heatsink, but with the Wing Boost fans on it there’s no complaints to make.
If we look at the actual cooling, though, we see that this 5-slot monster doesn’t keep up with the V1 stock cooler – which is already a good bit better than the typical AMD stock cooler – under Furmark BurnIn conditions. Idle temperatures are great, it takes normal applications like 3DMark’s Vantage, and similar games, easily with only the memory maxing out about 80 degrees Celcius. During extended Burning testing, though, this heatsink needs higher RPM fans to keep up with the HD5870′s extreme heat production. So to anyone living in a warm environment and serious overclockers: Get different fans, ones that can deliver more pressure with an agreeable sound production.
Pricing and Availability
The Alpenföhn Peter is generally available at bigger webshops but needs to be searched after a bit to be found. Using price comparison engines online really can help with this. I found Peter in the Netherlands at four webshops, starting at €54 and ranging up to €59. Germany asks at least €51 up to €69. A typical GPU cooler starts at about €25 and generally max out at around €45, making the Peter an expensive pick.
