Who all has removed the clutch fan from their 2012 Pro Climb. (M1100T or M800) I removed mine while riding and the clutch cooled down a lot. Put it back on and it was defiantly hotter with it on so I took it off and left it off.

We pulled them off right away. Sprays water on the clutches and rubs the side panel. Clutches are a lot cleaner with it off. I don't know about cooler, as I never monitored belt temps with it on there.

Removed fan and snorkel from side panel and it made a reasonable difference. No specific science to back it up just noted the an 083 lasted 450 miles in Sierra conditions from 2-4 foot powder days to cement conditions
Prior to that I had blown 2 belts on a Sierra powder weekend within 100 miles

Curious, what happens when the clutch without the fan/guard rubs on the side panel?
I worried about this also. So I am going to replace the bolts with some that will be flush with the clutch cap.

pulled it off! if you carve at all it will melt/destroy your side panel. it also grooves your clutch cover, and a lot of belt debree gets cought up in it causing an unbalanced clutch. it will still rub under extreme conditions but if you rivit some metal to the bottom of the panel to reinforce it from flexing it stops it all togather.

Once you reinforce the belly pan area nothing will rub.

When the first belt grenaded, it took the fan with it. Never replaced it.

Could you post pics of said reinforcing? Please!
sURE BUT ITS JUST A L SHAPED BRACK FOUND AT ANY HARDWARE STORE. BENT TO FIT AGAINST THE SIDE OF THE BELLYPAN NEAR THE CLUTCH. GEO POSTED A PIC OF HOW HE DID IT.

The clutch fans were a sales gimic. I didn't graduate from a mechanical engineering school but as soon as I saw that rediculous looking contraption I knew it would not work. The clutches suck enough air by themselves without the need of that silly piece of plastic. To prove my point, put your sled in a shop, garage, or outside on a calm day, open the hood and fire the sled up. Any exhaust smoke that circles around the engine gets sucked into the clutches. With proper venting around the clutches there will be no need for that anal roid.
1) Why put extra weight with a plastic cover and 3 extra bolts?
2) Why put a fan on the least powerful object in the sled to consume more HP as it revs up?
3) why trap heat when the aluminum will dissipate it faster and it has it's own air scooping ability since it is a triangular radius. They would have been better off making lighter more air efficient plastic clutch guard!
