I just wanted throw a shout out to the quality of their coolers. My daughters cooler failed tonight. Now most would be upset but this little cooler was the cooler that could! I purchased it to cool my E8400 that I ran at 4.2 daily and 4.5 for benching. It was for a 775 socket so almost 7-8 year old. She has used it for almost 3 years at stock clocks and the fan just gave out. Not sure on opinions of Zalmans but it will be a go to choice in air cooling for me
