I've got the 210s and like them a lot. If you offroad a lot I would definatley say to make sure that you seal up the control box. I had the fans go out on me this last weekend at Pismo dunes. The combination of sand and salt air caused sand to get in and stick between some components in the control box which kept the fans from turning on and I overheated. I took the control box apart and cleaned up all the components and it works as good as new now. Once I seal up the box with silicone I don't expect to have any more problems.

 

I agree with the seal idea. One idea is to get a water-tight box for kayaking. REI carries them. You could encase the control box, drill some holes where needed, and seal the holes off with silcone. Just an idea. The boxes run about $18 at REI.

 

I've had the 210's on for about 3 years and have had zero problems. (no overheating in S. New Mexico). My fans have had the vibration and I have talked to FAL about it. They told a buddy and myself that they are aware and are supposed to have a fix by the end of last month. I have been out of pocket so I haven't got back with them yet. Whei I first contacted them in the begining, the were very responsive and sent me new fan blades. Unfortunately it didn't solve the problem but it really doesn't bother me anymore since they have been reliable. I need to get back with them on the fix.

 

hook us up with that fix when you get it! tanks in advance-

 

I would call the cust service number. I have emailed (about an old fan I had) and never got a responce. 1 call, and it was done.
