Who are you a fan of?

Just kidding. ;)

Here's the real question: I got an extra dichroid head for the D5 I bought (which turns out to be a D6), and just found out the fan is not blowing, or starting rather slowly, if at all.

Anybody come across that problem, and if so, what's your fix? WD-40, machine oil or a new fan?

Thanks!

The bigger question is which celebs are fans of my work?!

Also just kidding.

Yeah, I'd try a little WD-40 on the bearings, being careful not to get any on the fan motor, to see if you can loosen it up.

If you don't get it working do a google search. I've seen similar sizes on a site somewhere for a project i was doing a while back. PC tower fans are similar in design.

Dear Imke,

Here is where I look first to replace things like that.

I suggest that you first try to determine why it's not turning or turning at proper speed. Issue might be it's crudded up (sorry to revert to a technical term, but it's the best I could think of). But could be electrical.

If dirt, I'd use an electronic cleaner or non-clorinated brake cleaner (my favorite for cleaning anything that doesn't talk back).

For lubricant, I'd go with a machine oil (like 3 in 1) applied sparingly.

Thank you all for replying!

It seems like the fan is crudded up indeed, since it WILL start, but only after some nudging, so I'll probably try cleaning it first. Thanks for all the suggestions as to where, what and how (now I can wipe that question mark off my face), and Neal: thanks for the link!

Cheers,

There is a possibility of WD 40 causing a problem if the wiring gets soaked.
Go to a Radio Shack or other electronics store and get a spray can of Tuner Cleaner. This is designed to clean electrical contacts and does wonders for slow motors. It is not as common as in the past, but still available if one searches.
