Xigmatek XLF-F1453

The XLF line reminds us of old Noctua S series which had lightly curved rectangular blades resembling airplane wings. The XLF-F1453 is another white LED and orange fan combination with other variants available in blue and black.


The XLF's are 3-pin models that ship with only a molex adapter and mounting screws. It's important to note the XLF has closed corners; many fan mounting schemes on heatsinks are designed to clip onto the inside of open corners.

Compared to most fans, the blades are anemic, with large gaps between each. Once again the blades are almost parallel to the struts. The acoustics of the XAF and XLF might be improved if they simply swapped housings.

At its top speed of 1,000 RPM, the XLF-F1453 had a mostly buzzy character but we also detected a barely audible hum which became more noticeable at 900 RPM. The hum was low-pitched and seemed to be partially generated by vibration (our foam frame stands reduce but does not eliminate vibration effects) which was not a total surprise given the fan's low weight. At 700 RPM it was much smoother but it also emitted a clicking sound which grew as the speed was lowered further.

A second sample was slightly worse with a more pronounced hum at both high and low speed.

Despite having a vastly different design than the XAF, the XLF performed more or less the same in our thermal test.
