Wathai 140mm AC Fan 110V 120V Variable Speed for Reptile Cabinet Cooling

They work well

Best unit out there. It managed to cool off my most powerful Ryzen 9 370 AI Mini PC by lowering temp by 12C on idle. Highly recommended, I will be getting more for my other MiniPC's. This little monster has some power, it uses 12V with a dedicated power supply with a variable speed switch. I bought before a ELUTENG Dual USB Computer Cooling Fan High Speed 120mm 5V USB which has a great construction but has a weak performance and didn't make any difference on any of my MiniPC's . This is the one you need to make a tangible difference in CPU Temps with the heating wave we're currently having in eastern Canada. It requires some basic assemble, manual wasn't that clear and overall design could be better, after assembling metal grills with screws, nuts, and plastic base which is great, a tip on the screws had some protruding that may cause some short circuit if leave it unattended, I used double duck tape to isolate and prevent any contact for each one of the four large screws, and have a piece of mind with my highly valuable MiniPC.

I have a vintage Technics SA-818 receiver from 1981. It's in Mint condition. It's been in a stereo cabinet for many years, and it gets warm,and if left on for an hour or more, hot. I recently decided to install a AC Infinity AC-ACT10 fan ventilation system, for $129.00 . Yes, this was am expensive cooling system, but, with its build and features, I felt it was well worth it. I got the ACT -10 on Monday, and installed it immediately. When I powered the unit up, it ran Great..! However, the EMI/ RF it created,shut off ALL reception to the FM tuner..! I contacted customer service, at AC- Infinity and they suggested a ferrite core bead, on the AC power line would eliminate the noise....WRONG.! It did nothing..! I returned the unit, the next day, but was still needing cooling for my receiver. I looked at this fan, and read many reviews, from others saying this fan worked excellently with their receivers. I thought for $14 I couldn't go wrong. I installed it as soon as it came today, and tried it with my receiver. The fan on the lowest setting, moves tons of air..! And, absolutely no noise on the FM tuner side..!! Sometimes, cheaper IS better..!! I highly recommend this product..!!!

I bought this fan to use as an extra cooling source for my FL2100-B linear amplifier. The fans in the amp work fine but I've always used. extra cooling to increase the life of the tubes. I was using a 12V 120mm fan, but it didn't have the RPMs I sometimes wanted. The speed on this fan is variable, which is excellent. I run it low when using SSB and a little higher when running RTTY or digital modes, where you can't hear the fan. At higher RPMs it is a bit loud, but that doesn't bother me. It sits on top of the amp, above the tubes, pulling the hot air out of the amp.

This fan is excellent for distributing heat in my apartment. The only heat I have is in my living room and I have the fan in my doorway that leads from there to the rest of the apartment. It’s quiet and I can control the speed depending on how cold it gets. It’s a great buy that I’m very happy with 👍
