Hi guys found a fan motor on e bay that never heats up
check out ,,,,,,, blue slim 7 inch 850 cfm 12 volt dc cooling fan..
same temp and conditions tested fans,
old o e m fan motor would run 71 seconds then would shut off.
this baby comes on only 26 seconds and has ten two inch blaces o e m has ten one inch blades . it pulls .18 amps the o e m is .34 amps ((checked with amp probe )) .it has 35 percent more free air space for air to
pass through to radiator,which does not come on very much.
temp gauge same comes on just above half way and goes
back below but takes longer to come on again.

Here you go ccoco, just click on the image below and it'll take you to the Ebay item you're talking about:

Click image for link

When I was searching the link I ran into the guy's store and it looks like he has the same item listed twice for slightly different prices, here's a link to that page. That looks like a very nice item at a decent price. If you need help in the future posting something you can click on my handle and send me a PM, that applies to everybody. Rich

I would recheck your calculations on the AMPS it draws that is an 80W motor.

Amps = watts divided by volts

So 80W divided by 12 = 6.66 amps!

Am I missing something If not that will drain your battery in no time.

The OEMs are usually 33W?

Wow, good catch Alley.....really good catch. Rich

[ccoco]

trike rechecked amp on blue fan it is only pulling .34 amps you are not subtracting
the resistence of the air hittig the gas tank whick lowers the electro motive force of the motor
fan can't cut enough air when blocked ,, same as blower motor on home a/c if you hold
your hand in front of the discharge the more you cut the air down the less amps it loads

[Alleyoop]

Ok, whatever its your battery.
What is the point of blocking the air to the fan I do not think that is a smart move. After all you are trying to get as much air as possible to cool the radiator down or motor whatever your trying to cool. Thats the whole point of getting a good fan, not get a good fan and then go and block the air from it .

bash>> i am an a/c and heating contractor, i live by my amp probe and air flow charts,,now.80 watts is the max you can run this motor any more then 80 the windings would start ot over heat. i checked in in place while running . thanks again don't know
how to p m.. been working on central a/c and window shakers ((window units)) for very long time thanks again for the pic

I see what your saying now c coco, .33 amps rather than 33 amps. That makes sense because I used a 12v fan from Silicone Intakes that was really stout and it pulled about 2 amps. We had some guys asking about amp draw from your other post with the picture. I'll link that to this thread so they can read your thoughts. Rich.
