I used this with the 25mm USB fans. It works great.
Wonderful experience, got my order super fast and very excited to find a source for little fans with a USB plug, I've been looking forever for these and work perfect in my tropical vivariums I build.
I Purchased several various USB cables. They arrived very timely and all were perfect.
I would certainly purchase from them again.
Excellent product. Great and friendly staff. Quick shipping . Quality products.
Coolerguys have been great, this is my second order with them. In my first order one of the fans was faulty, after sending and email within a few hours had a reply and a new fan being shipped to me at no extra charge. Very pleased with the product using them to cool a Denon AVR and with the auto temp controller it works superb. Will use again.
