A big thank you to Glenn. He knows his stuff and is very helpful. For me, this is the only place for these products.
I have had a Cooler Guys cabinet cooling fan kit for about 10 years that recently stopped working. I replaced the thermal controller to no avail. After discussing the issue with customer service through the chat feature they determined it was most likely just the power supply. They set me up with the right product and my kit is working perfectly again! NOTE: After examination my old thermal controller also had a blown capacitor and needed replaced anyhow.
