Thanks Moggy. I will get one ordered.

Edit - bloody Maplin. None in my local branch and you can’t order them on line. Nearest one is 20 miles away!
I’m sure this used to be a good company.... :evil:
Will continue the search.
Thanks Moggy!
Hi Lardo would a internal laptop fan like this one be any better.

It would blow out of the side of the case also maybe not too tall for the ZX case.

A couple of things to keep in mind with these inexpensive sideways fans:
  • They often use sleeve bearings rather than the better ball bearing type,
  • They are normally much less efficient at moving air compared to the normal PC fan type,
  • Often they are noisier than the normal PC fan type.
But still may well be worthwhile getting one (for that price) to see how well it performs.
