Wathai80mm x 38mm High Static Pressure Fan 12V 4 Pin Dual Ball PWM 8038 High CFM for PC CPU Cooler GPU Server Computerc Case Cooling

Good quality good airflow slapped right in for a replacement no problems but it is not silent like my previous fan but that's fine as my workroom has plenty of ambient noise anyway but I can see it being pretty annoying in a very quiet environment

50%越えるとケース内から、「ウィーン」と聞こえますが風量はかなりあります。ケース内の冷却したいデバイスにピンポイント設定し、指定温度で一気に廃熱したり空冷目的で使う設定すると効果抜群です。

I have a Dell 7060 MT I7-8700 (mid-tower) desktop I recently purchased and upgraded. One of those upgrades was to replace the original case fan with this fan. So a couple of things to consider. The original fan was 12V / .36A and rated at 40 CFM, and was whisper quiet. This fan is 12v / .45A and rated at 65CFM and is not whisper quiet, but is not in my subjective opinion very loud.In fact I like being able to hear it because I know it's working and have no false sense of security. I should add that I have been in IT for many years and am therefore innately suspicious of electronics in general. But I digress.So here's my end game - this fan generates way more air flow that the original. It spins at a much faster RPM and has almost 3 times the number of 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 air flow is way more than the difference in the specs would indicate. My internal 512GB SSD (Win 10 Pro drive) dropped 5 degrees F and my 3T HHD (data drive) dropped 7. Well worth a little additional background noise because heat is a common killer of any type of drive.In addition to having the same DCV rating of 12 it's also important to use a replacement fan that has the same or lower current rating. A little higher difference is ok in *most* cases, again depending on a number of system variables. So to be absolutely safe use a fan with the same DCV and an amp (A) rating the same or less. In my case new fan's .45A was close enough to the old of .36A to not matter.Installation was easy as far as the new fan goes. Getting out the old fan was a pain in my case (no pun intended). However, I did have to trim off a piece of the new fan's 4-pin connector on its backside in order for it to fit into the socket on the motherboard. You may, or, may not, have to do that. Good luck!

This fan moves a lot of air, and for this reason is noisy. It works very well.

Bought a used Isilon storage server and the fans that were installed plugged into a daughter board. This caused them to be on 100% power constantly which, for a server room wouldn't be a big issue but too loud for my living room.These were a great replacement and fit perfectly, plus was able to plug into the motherboard to allow fan control from the bios. Perfect.
