I don't know about the UT (I'm still using the stock heatpipe construction), but on the DK, the HR-09 Type3 work very well and give me good temps, compared to the stock mosfet coolers.
Temps under load are now in the low 40's. With the stock coolers, temps got up to 70°. The coolers feel pretty cool to.
