it's out of stock, but im 90% sure you can

I would say if it's made to fit a 501 then it better darn well fit 100%

Now if it will fit a C1 host is a whole other question why
aren't you asking the person who made it :thinking:

The important dimensions are listed, the two diameters are 22.5mm and 27.5mm.

Eudaimonium makes these heatsinks, you might ask him for more details.
