Getting a software based 3 pin fan cooler?

[boed]

Hello,
Because of my case design, I need a 10mm thick 3 pin fan between slots for my raid controller. I put in a 1000 RPM fan and it just is enough for medium load and very quiet (about 14db). However I could really use a 2000 RPM fan for heavy load which will make it too loud for normal use (about 30db)

I was looking at something like this

However the back of my case is difficult to get to under my desk. All my front bays are full so I can't put a controller there. I was wondering if there were any software based controllers?

Cheap H/W way to control a single fan, Zalman Fan Mate $8.99 - can be mounted external, with supplied pad or left to dangle and attract stray cats.

Pure software solution, there's Speedfan - a classic, with a tweaker's interface.

At the top end, could use the Aquaero 5 LT - USB controller, but really 'spensive way to control a single fan.
