-1 the process of sweat evaporating when being blown by a fan will cool you down

I've bought two, I plan to put one downstairs blowing cool air in and one upstairs blowing hot air out!

The 18" one is 140 watts according to CPC so if you have it on for 4 hours per day for a month then you're looking at about £2.50. However when you actually consider the length of a british summer as being only a week at most then you're only looking at like 60p extra to keep cool during that period...

Exactly (and before someone pipes up, we mean micro sweat, not full-on, dripping 'exercise sweat'), that and something called 'wind chill' that apparently people have never heard of.

Fans aren't exactly snake oil...

Just buy a granite house.

Doesnt matter what the temperature is outside - its always baltic in my gaffe.

Not so much fun in the winter though.

I love the summer and outdoor spitroasts

had one years ago.It sounded like a Spitfire in my living room!!! :wink:

tray of ice cubes in front of fan to circulate some cool air. makes all the difference if your in a small room with no windows

Ordered 4

Point it to blow out of a window rather than at you. the noise goes out of the window too

remember the heat last year? yes, I think I remember that day.

LOL

Well, my fans both arrived today - I selected the free 3-5 day delivery and they came next day with DPD. I won't argue against that. Just putting them to the test now!

Lowest setting: Sounds like you'd expect any big fan to, like a propeller plane taxiing on a runway
Highest setting: Sounds like you are sat on a twin propeller plane flying over a rainforest canopy

Overnight, I might play some soothing rainforest sounds and see what dreams I can conjure... if there are headhunters, I hope I'm on their side!

Suitable if you want a less powerful fan too.

If you don't want to wait for delivery and have a screwfix nearby it maybe worth checking this out

Ordered the 20' fan. Looks like they are a good £15-£20 cheaper than Amazon. For cooling a bedroom at night is there a best place to put the fan ? By the door window, furthest away or does it not make any difference

since the fan is not travelling in my room while switched on so better call it high speed than velocity...

OK, seeing as you seem to be going round in circles, I'll leave it there. Don't forget to update us when your overunity machine is patented.

don't feed the troll

Ice cold?! You devil

No it does not.

The air a fan draws is through the back of the grill - the fan blades rotate in such a way that it causes air to be sucked in from the back and blown out from the front. Try spinning the fan blades in the opposite direction and the reverse becomes true - air is drawn in from the front and blown out through the back.

There are fans in the motor which prevent it from overheating.

There is very little heat drawn from the motor and blown out by the fan so you are completely incorrect.

Stop basing your assumptions on a basic theoretical knowledge of physics, and study the engineering aspect of a motor, and of an electrical fan.

hehe, that depends... you need to be more precise. And, scientific evidence supports the argument so how can we be deniers?

This confuses me too, but I'll try (cos I'm bored!)...
There was no real temperature change so No it didn't get cold, but the air at body temperature directly in contact with the back of your hand was moved and the air that replaced it moved too quickly for it to reach body temperature so that part of your skin felt the cooler air (or more precisely, it was able to transfer more heat to the cooler air - because the rate of heat transfer increases with the difference in temperature) making that part of your body appear to be cooler (because we feel cooler the quicker we can transfer heat away from us)... but it wasn't really.

Go into you kitchen on a cool day and touch all of the different surfaces and tell me which one is coldest... and then check the actual temperature of all of the surfaces with a laser/non-contact thermometer thing... then tell me who the denier is :stuck_out_tongue:

i suppose the more we use the fans to cool us down the more electricity we use, thus increased climate change so more fan use until we all cook.... but at gas mark 7 instead of 8 cos of the fan assistance.... ding... pizzas done.

Err, can one of the fan cooling deniers stop with the physics for a moment and blow on the back of your hand. Tell me it didn't go cold....

By blowing air around, the fan makes it easier for the air to evaporate sweat from your skin, which is how you eliminate body heat. The more evaporation, the cooler you feel

+1... and all of the extra evaporation is also adding to the room temperature (despite you feeling cooler). It's still nice to sit in front of a fan on a hot day though :stuck_out_tongue:

best I saw on here was almost 9 years ago for an Argos challenge 18 inch high velocity fan at £14.99.... but deals like that are hens teeth and I ain't waiting any more summers for something like that to come back around...

​Why don't you post a link to the £6 fan then?

Proof or it didn't happen.

I think you've missed my point entirely. As any motor is not 100% efficient i.e. some of the input energy turning the motor is turned in to heat as a result of resistance etc.
“Energy cannot be created or destroyed, it can only be changed from one form to another.”
This means that the heat ends up being drawn through the fan as extra heat load in the area you are trying to cool, which as you say is what the "cooling systems in the motor" are designed to do, so not sure of your point?

I think Morrisons have got big blowers like the one pictured for £25.

You can't be serious if you think this is a good price for the fan? I kid you not i bought same size fan for exactly £6
.4,550 in stock ready for despatch (UK stock)

Lets see tomorrow how many gullible there are..

​not exactly, air flow assists evaporation so helps your skin to cool you.

Perfect for the turbo, heat added.

Cheers

You're over analysing, have you ever looked inside a fan and at the motor specifically? There are cooling systems in the motor which is why the motor does not burn out from overheating after being used day and night.

thanks - bought for a very hot very small cafe!

I did use this when I was sanding some Victorian sash windows to blow all the dust into the street rather than hanging around in the room (lead paint and all that orrible stuff). Poor old pedestrians in the High Street didn't know what was making them sneeze so much! Boosted the chemists sales though.

I got this fan deal last year and works great with a portable air-con unit downstairs with this pointing out of an upstairs window. It solved the problem of all the heat rising upstairs and a chilly downstairs. It isn't that noisy if it is blowing away from you.

good way in blowing dust in your face from the floor!

I will stick with keeping my windows open and downing a few cans of ice cold Guinness.
Heat for the fan tho.

Don't forget the energy that is converted into heat from the motor and blown in your face.
Oh, and the sweat will only evaporate if it's not too humid.
Hot deal though, I have a similar fan and it's excellent.

​Am using mobile....will have a play and find out

Took delivery of the 14" fan today, good for small rooms and its not noisy.

Does not do that for me? Virus or Malware on your pc?

Does anyone know why when I click the link, instead of directing me it comes up with a file download page?

Exactly (and before someone pipes up, we mean micro sweat, not full-on, dripping 'exercise sweat'), that and something called 'wind chill' that apparently people have never heard of.

Fans aren't exactly snake oil...

They are loud but only by movement of air. We have had one for a few years, I recommend them.

Blimey, for years I used to think I could keep the frozen food in front of mine.. silly me!

-1 the process of sweat evaporating when being blown by a fan will cool you down

I think it's a great deal as they range from 31-50 on Amazon

Great to know, cheers.

Can anyone recommend a good extension lead?

Noisy*

I own this as I bought it last year noise af... But does the job very well

Just buy a granite house.

Not so much fun in the winter though.

Do these have a variable speed control?
Edit: just seen in the catalogue page (but not the web page) "3 speed settings"

@umirza85 I read this here:

http://www.hotukdeals.com/deals/pro-elec-18-high-velocity-fan-26-83-cpc-farnell-1910250?page=1#comments

"i have the 18" screwfix version which was a similar price as this when i bought it, it is very good but even at the slowest setting it is very noisy. the motor is nearly silent, the noise is just the airflow so it cant be helped- if you want to shift a lot of air, its going to be noisy. on hot nights we put it at the bottom of the stairs pointing up and it circulates the air for the whole house"

So seems it's for a different, albiet similar, fan

Thanks for the clarification. That is something I don't mind. I was more worried that it would be the sound of the motor that is loud. I prefer something that will move a lot of air and understand that it will produce some noise. It's the cheap ones with the loud whining motors that I can't stand.

Cold for inciting heat-red

+1 pointless, there like a car without AC, just muggy air getting pushed back into you. I will stick with my ice pop down my back

@umirza85 I have heard even on the lowest setting they can be quite noisy because of the volume of air they're moving

@Danze1984 That's a good point, excellent for turbo trainers and bike rollers too!

Ordered one, cheers OP. Doing weights will be a bit more comfortable in this weather now.

The problem with fans is that they just circulate warm air

Moved here from a place where AC is the norm in houses. thought I would be OK but it was the nights where it was too hot to sleep that were the worst.

How is the 20" version of this for circulation/noise?
