ZALMAN's ZM-F4 cooling fan is a very unique product. For starters, it's called a 135mm fan, but it's actually able to mount into most 120mm spaces. That means that you can upsize pretty much any 120mm fan giving you the air flow of something a little larger. Check out the video review below for all you need to know...
The quality of the ZM-F4 is fairly solid using an advanced sleeved bearing that claims a 50,000 hr lifespan and seems to spin easily and quietly in our testing. Further noise reduction can be had by utilizing the included RC56 resistor and does make a noticeable difference. While the silicon grommets are normally a benefit to noise reduction, my experience with them hasn't been as positive as I've had them snap on me before. I generally like to use normal case screws, but unfortunately, none were included with the ZM-F4. Nor were there any real instruction leaflet as they were just printed on the box. Had I not known this, I would have ripped the packaging up completely to get at the contents.
At $14.99 US MSRP, the ZALMAN ZM-F4 is very reasonably priced and could potentially be both a cooling and noise reduction upgrade for any case or CPU cooler sporting the more common 120mm fan size.
- Converts most 120mm fans to 135mm
- Quiet operation and long life
- Reasonably priced at $14.99 US
- No conventional case screws included
- Would like to see printed instructions
