My only qualm with the ISGX-300 is that when installed, it interferes with tall memory sets, such as Corsair with the DHX heatspreaders. So, if you have that memory, you are out of luck because the cooler cannot be mounted in a front to rear facing way - only in a top to bottom facing way. If the cooler could have been mounted with the longest sides up and down, and the fan to the rear, then tall memory could fit and there would be no problem. It would have been nice to have a second set of fan retention wires included, in case the user wanted to purchase a second ISGC 12 fan and mount it on the other side of the cooler for maximum cooling. If you are looking for a great performing cooler that is nearly silent, then the ISGC-300 will make your day.
