Unlike many aftermarket AMD-compatible coolers, the Dynatron G950 uses a bolt-through design and as such, requires the removal of the stock retention module for installation. Given the massive size of the cooler and near 800g weight, I'm happy to see this type of attachment, rather than the standard 2-point tension clip. Not only will this provide a much more stable and unmovable mounting point, it should also yield a bit more seat pressure for better thermal transfer.
Unfortunately it also requires a motherboard backing plate with fully-threaded posts, so that the spring-loaded screws have something to get started on. This particular board comes with a plate with plastic posts, which I found to be common among many of the other AMD boards I have on hand. They are threaded only at the very bottom, so the G950 would require Dynatron's optional DY-PBK-AM2 backing plate for installation. Once I had the requisite part in hand, I could remove the motherboard, swap out the plates, and continue with the installation.
With the correct plate in place, the thumbscrews require only a slight push and twist to get started on the threads, then it's simply a matter of tightening them down. I did have a little trouble getting to the two stuck between the cooler and the bottom of the case since this is a BTX format, and I had to remove the video card to access the two on the other side. The tops of the thumbscrews are not slotted for a screwdriver, and the overhang of the cooler would make it impractical to get a tip in there anyway.
Although it uses a PWM fan, and speed in relation to temperature can be adjusted in the motherboard BIOS. I left the G950 run at full blast which averaged ~1785 RPM. That's within 1% of the fan's rated max speed. Even so, the cooler was whisper quiet while still maintaining a decent amount of airflow out the back. OCCT was used to generate load temperatures at two different levels of overclock.
This 90nm Windsor dual core has a 125W TDP rating, and when overvolted it can really generate a lot of heat. Fortunately the G950 had no problems handling that, Dynatron rates it for 130 to 150W processors. While it didn't curry the best temperatures this CPU has ever seen, it did manage to prevent it from getting to 60° C at which point the system typically locks up. That's more than some big name brand coolers can boast. And it did so with only a rated 26dBA of noise.
Let's wrap things up with some final thoughts and conclusion.
