Wathai 80mm 24V DC Brushless Cooling Fan 2Pin 24Volt High Speed Amp Fan

I use a Crown XLS 402 for my home theater, and the loud cooling fans are noticeable during the quiet parts of movies. The amp uses two 12V fans that are run at full power during normal use, and overdriven at 19V when it's run hard. I replaced the original 12V fans with these 24V models so they'll be running well below their max rating at normal use, and within their envelope when driven hard. I don't have the equipment to measure the sound or airflow, but by comparison the airflow seems comparable with the new fans - and they make about half the sound the old ones did. Honestly, I could probably try an even lower powered fan, but I want to keep the airflow high for longevity so I'll quit while I'm ahead. My amp didn't have plugs for the fans, so installation required cutting and soldering of the wires. Other than that, they were a one for one swap using the existing screws and mounting holes.

I bought this fan to replace a failed fan in my TrippLite 1500 UPS. Since the UPS is in my Master Bedroom, I was concerned about noise. This fan was quieter than the original fan, and it works perfectly. I'll even be happier if it lasts 5 years like the original fan. This is an excellent fan for the money!

These are pretty good fans. They move a good amount of air and are not too loud. Describing loudness is subjective, so I would describe the spectrum of loudness as silent, whisper, normal, noisy, and loud. Based on that, I'd put these between whisper and normal, if that helps.

In building my DIY CNC Plasma cutting rig, I gutted an old desktop PC tower to use as the CNC control box. I shopped pretty hard to find the best blend of low cost, high output, and low noise. I finally settled on and bought this 2-pack of cooling fans and installed both of them in the tower. I'm very, very pleased both with the air output and the relatively low noise! This was a big win. Keeping my drivers cool!

Works perfect to cool 24volt motor for continuous operation.

Replace the noise fan in my Hartke HA5000. Fit perfectly, noise is much improved, and easy swap out once you've removed the hundreds of screws holding the case together!

I've been using these in Peavey and Crown Amps. At amp low temp they run perfectly quiet on 12V & at amp hi temp they are still very quiet at 24V. I put a white dot on the fans hub to visually make sure they were running as they were so quiet at lo temp. The church the amps went into are very happy. SHHHHHH!

Ok.. these 24v dc fans are junk. Wired up on a 24vdc system and they both went bad in seconds..

Nice fan. Super helpful that they provide a metal shroud for safety... a lot of brands don't do this... It was a perfect addition to my 3d printer... they are relatively quiet and provide good airflow.. thank you Wathai!

The fans are nice and quiet would buy again

24VDC 80mm fans These fans move a lot of air for 80mm but are VERY noisy. 27db is barely audible (it's almost silent) and these fan are VERY audible. When both are on, it's not bearable. Removing them and looking for something WAY quieter.
