Review on 🌀 Wathai 80mm x 25mm PWM Fan, High Speed 5000RPM 12V 4Pin Fan, DC Brushless Cooling Fan, Large Airflow Fan by Sean Fabacher

I have a Dell 7060 MT I7-8700 (mid-tower) desktop that I recently purchased and upgraded. One of those upgrades was replacing the original case fan with this fan. So, a few things to consider. The original fan was 12V/0.36A, rated at 40CFM, and very quiet. This fan is 12V/0.45A and rated at 65 CFM, it is not silent but not very loud in my subjective opinion. In fact, I like hearing it because I know it works and I don't have a false sense of security. I have to add that I've been in IT for many years, so I'm wary of electronics in general. But I digress. So here's my ultimate goal - this fan produces a lot more airflow than the original. It spins at a much higher speed and has almost three times as many blades. Hence its relative noise to the original. I could barely feel the air from the old fan with my hand, but this fan's airflow is much greater than the difference in specs would suggest. My 512GB internal SSD (Win 10 Pro drive) dropped 5 degrees Fahrenheit and my 3T HHD (data drive) dropped 7 degrees. A little extra background noise is worth it, since heat is a common killer for any kind of drive. Also, with a DC 12 rating, it is important to use a replacement fan of the same or lower rating. A slightly higher difference is acceptable in *most* cases, again depending on a number of system variables. Therefore, to be on the safe side, use a fan with the same DC voltage and current rating (A) or less. In my case, the new .45A fan was close enough to the old .36A that it didn't matter. Installing the new fan was easy. Getting the old fan out was a problem (no pun intended) in my case. However, I had to cut off part of the new fan's 4-pin connector on the back to fit the socket on the motherboard. You may or may not need to do this. Much luck!
