Another potential option for others who like me live in baking hot Equatorial England is to combine floor-level Clevas with high-level pedestal fans.
In this setup I’ve a pair of original Clevas on a remote plug (so need to pre-select the fan speed on the two Clevas, unlike their latest fan) for cooling legs and lower torso, with a couple of these 16" remote-contolled Prem-I-Air 16" pedestals covering upper torso and head duties and which I’ve been able to position right up close for maximum coolage.
I paid £30 each for those Prem-I-Airs via Amazon, choosing the “2nd hand” option, which are actually brand-new returns from other customers with no sign of usage whatsoever. These have fan speed control from the remote, and both fans respond in parallel from one remote. The whole setup of four(!) powerful fans + remote plug for the two Clevas cost around 10% less than one Wahoo Headwind and offers serious coolage.
In use, I find turning the fans on/off up/down via the remotes before/during work intervals acts as a bit of mental distraction akin to the to the old “changing hand positions” tactic that plenty of us will be familiar with.
