After this first attempt, I decided to fit a single slim line 70mm fan to the NT01. This turned out to be slightly misaligned as you have to fit it offset by using a screw hole from the second 60mm mount, which means that it doesn't cool the whole heatsink. Fitting this did wonders for the CPU temperature, which never peaked over 50 degrees Celsius at idle - much more in line with what you would expect from a decent CPU cooler.
