Steven Van Eycken van Overclockers Online heeft een review gemaakt van twee harddisk coolers; de JustCooler HD-100 en de HD-600. De HD-100 maakt gebruik van twee 40mm fans die elk ongeveer 5CFM airflow op everen door 2500 rondjes per minuut te maken. De HD-600 gebruikt één 55mm fan @ 3500RPM, die 18CFM opbrengt. Over de HD-100 is de reviewer nog redelijk positief, maar voor de HD-600 heeft hij eigenlijk geen goed woord over:
The second cooler I tried, was the JustCooler HD-600. This cooler clearly performed a lot worse than the HD-100. The HD-600 only cools down the bottom of the hard drive instead of blowing air over the entire hard drive (like the HD-100 does). Another bad thing is that the HD-600 uses the (hot) air inside the case to cool down the hard drive instead of sucking fresh air into the case (again, like the HD-100 does). All this resulted in the hard drive still being warm at the top even when the HD-600 had been working for a couple of hours.
[...] Although these two coolers are made by the same manufactor "JustCooler", they are both very different! The HD-100 is a very efficient hard drive cooler, which can take good care of your precious MP3z and nude pictures and it'll even lower your case temperature by a couple degrees. Then we have the HD-600, this cooler (if we even dare to call it a "cooler"?) is the worst hard drive cooler I've ever seen in my entire life! Oh man, if you're desperate to buy a JustCooler hard drive cooler, I suggest you go for the HD-100. If the manufactor doesn't have to be 'JustCooler', I'd say you better check out the I-Storm II cooler from Globalwin.
