I think the desire for "more fan" isn't the answer. Do good air management, use less power, have less of a hoover on your car. Of course, that's not the "easy" answer.

Its pretty simple to test the effectiveness of any fan and duct work.
Run your car and take temperature readings.

I haven't created much of any duct work to speak of for any of my cars, however I have tested and tried about 5 or 6 different fans, ...the WTF's have brought my motor temps lower by about 7-10 degrees consistently and at least 5 degrees cooler than any other fan I've tried. I attribute that to the amount of air they are pushing.

That's exactly what I'd attribute it to. Now, imagine if you have good airflow on all sides of the motor, instead of one side. Or.. if you have a motor with ventialation holes, ducted air through the stator.

I'll be trying it at some point. but I've got a lot of things ahead of that.

Using the same fan, on my computers, I saw 20 degree reductions in core temperature by doing ductwork to stop reingestion of air. For an open fan, something like 30% the air that comes through it, is re-ingested air. And in this case, is pre-warmed.

Makes sense! ...I am building up a new TC ...I may experiment w/ duct work a bit more on this build (you've inspired me).

My favorite ducting is by Layne spec

That's an attempt, but not a good one. :-) I"ve seen those around. I"m sure that helps reduce reingestion of air, but it's not gonna do much for getting air all around the motor. I think the cobbled lexan ducts I"ve seen would be more effective than that.

So after more testing and checking ALL my WTF 30mm fans, it seems like the fan I showed in my video was the only one having a problem with the motor's magnetic field. The rest of the other WTF fans spin just fine even touching the motor casing.

My newly acquired WTF 30mm fan will stop dead when in close proximity to certain parts of the 12T brushed motor in my Traxxas 4-Tec. At first I thought my fan was bad and ordered another one till I figured it out. lol Can't get too close to the motor! However, I've noticed that there are certain spots on the 12T motor that have much less of an affect on the fan. Perhaps this is the gap in between the magnets. For some reason, this doesn't seem to be a problem with my TSR brushless motor. Although I haven't tried moving the fan closer than 10mm or so or in different positions around the TSR motor. Fan works great on my TSR.

On another note, Can anyone tell me what the square blue piece of plastic (might be clear plastic with blue protective film) that comes in the bag with the fan is for ?

so.. I'm lead to believe that these fans are just relabels.

Wild Turbo Fan, RC Car Fan, RC Cooling Fan, Heat sink fan, RC car accessories, RC car, RC

That indicates it's the first fan that's not just a relabel. I think they're just running 5v fans at 8.4.

I was really hoping these were custom.

That would explain the two out-of-box failures I had. But then there's also the one I bought used, and it's on its third year of use.

It probably explains that too. If you're using generic parts, from what may be multiple manufactures, quality control is going to be something that's not easy to assure. running a 5v fan at 8+v ~does work~ (I've tried it... with generic parts I've pulled from other places)

I need to spend an evening with some lexan :-) Get a duct worked up so I can do some real testing.

​​​​​​
That piece of lexan is used to direct the airflow into the motor, like a simple shroud. Just use double sided tape and stick it on top of the fan.

That's quite disappointing but makes sense after having 2 40mm fans completely die on me with no reason. I've only had TDX fans die on me after getting rocks stuck in them or having a bad crash and the fan coming off the sticky tape.

Check on Amain.com because I just brought the connectors from them.
