Computer DK heeft een vergelijking gepost van een KryoTech en AseTek supercooling systeem. Hier een stukje over de upgradebaarheid van beide systemen:
ASETEK has a huge advantage when considering your upgrade choices. You can basicly use whatever CPU/motherboard combination suits you best. Only limitation at the moment is that it has to be a Slot 1/A motherboard. If you have a Socket370 CPU, you can use a slot converter. ASETEK currently has systems based on Celeron, Pentium III and Athlon. ASETEK has already said they will support Coppermine from the moment it is introduced. They are the only company which offers a dual-CPU system. Kryotech is talking about having a dual Athlon ready around late Q1 2000, early Q2. If you buy a dual system from ASETEK, you would be able to change to dual Athlon the very same day dual Athlon motherboards are available (let it be soon.... The only thing you need is a CPU kit which costs around USD30. It is up to you if you want to change the CPU(s) yourself or let ASETEK do it for you. It is still not quite as cheap and easy as upgrading a non-cooled machine but it comes close.
Kryotechs system cannot be upgraded. You are flat out of luck, which makes a somewhat grotesque investment for the average gamer. (We did not manage to get an answer from ComCool before deadline as to whether they were able to upgrade the machine for you and if so, what it would cost).
