I have an old Promate Prostration.3 that I bought years ago. I generally use it to lift the rear of the rMB when on the road for ergonomics. The cooler has a very small footprint, with adjustable width (7" - 15.4") that allows you to place the fan directly under the CPU`s heat sync. My own 1.2 will run at > 2Ghz indefinitely with this set up;

The Prostaton.3 is approximately a third/quarter the size of the rMB. FWIW rMB is the only portable Mac that I have observed that a powered cooler can make a significant difference to performance, should you require it.
rMB 1.2 holds 1.9GHz - 2GHz with all Core`s lit up holding at around 8W plus power consumption (CPU only), it will then drop off to 1.3GHz, surging back to 2GHz, as thermal throttling is in effect. Placing the Notebook on the Prostatation.3 with the fan on, you can literally see (
Intel Power Gadget) the MacBook recover from the throttling event. The 1.2 MacBook will now hold 2GHz, as long as the cooler is running...
