Either way it turns off at 87.5mph

hmm. simpsons told me to keep it because when turned on it would help with cooling. didn't know it would switch off after 87.5mph but during a slow corner it would drop below 87.5mph does it turn back on then? does the fan stay on until speed is high for a while or does the fan stay off until speed is low for a while? this makes a difference on track obviously.

Well I suppose if you race in a hot day and you are using the AC, the fan will be needed in the slow corners.
But the fan does restrict air flow, check here -> http://www.cslregister.com/forum/sho...t=10735&page=4
