In reply to Andrei Istratov. I think you right ! but maybe someone will receive money for some ad-vice ; )

Huge important area that I haven’t gotten much traction on with others. I hope your article is wake up call. Bit I have some things to add and hey everyone don’t read too long and you won’t believe me so lol keep your headwinds and ride on lol ;-) 3) bruh does anyone have a fan? Nah. (Like, not anything remotely close to what’s useful). Check out tornado 24’’ drum fan yellow is up to 8000+ cfm now red one higher AND they tuned them do less decimals … amazing. I set up my yellow and a ‘cooling down’ much smaller fan attached to smart plugs but within reach so can easily manually hit the buttons on it too. $120 ish. Yeah, you can afford it. 4) pedestal fans (vs floor fans) will cost more for same air movement bit the above company has some and if you have a cycling ‘desk’ it’s hard to get the flow right from the floor. Don’t buy a fan that doesn’t list cfm and have lots of reviews. There may be others but I don’t see anything as good with cfm price noise as the above one. They make call mounted ones too if have beams to screw then into. 4) the air movement dynamics are hugely important: if the fan is near a back wall in a narrow room where’s the air coming from? I have min now on one side angled slightly towards the wall it’s near directly at my near that side wall, and if you stand in the other side of the room you can feel the wind of the air coming round to go through it. Moving other air inhibitors out of the way makes a difference. 5) more than one fan so can titrate more than one big one on off good too…but remember ‘how is the air circulating in here?’ And tweak configurations it makes a huge difference. Agree compared to no fan it’s like 20-25% difference in watts going hard like 50 watts night and day. Your mileage likely won’t vary but like other stuff Eric writes aboit in plain site and others additions it’s all here I hope this is helpful for at least some out there

I’ve been waiting to post a comment on here as I tested a bunch of fans. I have found ‘the one’ and figured I would share. Fair warning: this is not cheap but you only need one of them. The XPOWER FC-250ad fan. Here’s the link: https://smile.amazon.com/XPOWER-FC-250AD-Circulator-Blower-Outlets/dp/B08642SFWZ/ref=sr_1_1?dchild=1&keywords=xpower+fc-250ad&qid=1611273443&s=home-garden&sr=1-1
I wrote the longer review there on Amazon that goes into detail, so I’ll spare any readers here from regurgitating all those words. Basically, these specialized air mover and water damage remediation fans use a whole other design and are engineered to send this concentrated beam of air that can literally blow the glasses off your face at 10ft. No industrial drum fan moving several thousand CFM can come close to that because that’s not what those fans were designed to do. I strongly recommend you look into this if you’re having cooling problems while riding indoors. I’m in a fairly warm climate year round so cooling while riding and racing indoors is, er was, a challenge.

In reply to C.R3. How were you able to connect these? I also have a few fans laying around and think this is beyong brilliant. Id like some maybe pointing at my head from under my handle bars (not sure if it will work with towel) but just thinking allowed here. Very cool you used PC fans!

Since I haven’t seen yet anywhere, I thought to share my way to avoid bathing in my own shoes since I really sweat a lot. I took 3 old 12V PC fans, 2 120 mm fans are located at the rear brakes to cool my legs from the back, and a small one located at the head tube.

This is great, Eric! However, there seem to be a contradiction in your logic and recommendation. You pointed out that one should have as many CFMs as possible to simulate natural cooling why riding indoors, ideally 7,000 to 9,000 CFM. However, it is easy to calculate that Wahoo Headwind, which is a great smart fan, produces only about 440 CFM. Wahoo does not specify CFMs, but one can estimate air flow from spec of 30 mph air speed (13.41 m/s) and area of the section of the fan through air is pumped, 14.5×10.75 cm = 155.8 cm3=0.01558 m3. Multiplying one with the other, we get 0.1089 m3/s, or 12.535 m3/min, or 442.7 CFM. I own a Headwind, and it is adequate for most conditions, even though for me it fells short when it is summer-warm in the house. But then, if 440 CFM is enough and it is best of the best, one can ask, how can it be enough if natural cooling is 7,000 to 9,000 CFM, i.e., up to 20 times more? Actually, I think I know the answer, or a part of it. The most cooling is needed when we generate most power, which oftentimes is climbing. When we climb, speed is relatively slow and natural airflow is modest (at least for me). We may be getting more cooling than we need when riding on a flat terrain or downhill, and less cooling than we could use on climbs. A smart fan reverses that, providing the max cooling that it can provide when we generate most power or have the highest heart rate and slowing down when we need it less. Also, it is so directional that it blows, basically, only on the torso, which could be an even smaller area than in your estimate. It still defeats common sense how it can be enough, but it feels enough most of the time!

this is the fan i use, the remote is a dream. https://www.amazon.co.uk/gp/product/B085ZFYW2Y/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
