The only time that I've been concerned with not getting sufficient cooling is:
CROSSING the INTERNATIONAL BORDER between the US and CANADA
...particularly at Blaine, WA (near Seattle).
Coming SOUTHBOUND (into the US)...it is not uncommon to see 2 lanes of traffic with over 200+ cars in each lane waiting to cross through US Customs.
That 45 minute - 1 hour waiting time would put severe heating conditions on a bike "inching" ahead.
(You could turn the bike OFF and push it about 1 mile).
Spend $50 (no fans required) and apply for (serious security background check and personal interview required) and get a NEXUS card that get you into a SPECIAL...no wait...LANE.
Buzz right up to the head of the normally EMPTY lane...FLASH your NEXUS CARD...and you're home free***
PS...getting the NEXUS card now automatically enrolls you in the US Customs & Border Protection GLOBAL ENTRY program at International Airports in the US. So...whether you're riding the bike or flying into the US...this is a great deal. No waiting at airports...special lane...you're home free***.
(***You must comply with all the very tight entry/customs restrictions on the use of this card or it can/will be confiscated and you'll never get it back)...per the issuing officer.
If it IS confiscated...you've obviously got some serious 'splaining to do.
