I don't think you can get aftermarket blower coolers can you? Why do you need one, is the old one knackered? Replacement fans are available. I doubt an aftermarket blower would perform better than a stock one.
You may find a used one on the bay.
That cooler is 13 years old and rated for cards of 84W TDP. It simply won't keep up with a modern card with any real heat generation.Was looking at the Akasa Vortexx - the mounting holes are 53mm. Not sure about the precision of my measurements but they seem to be 52-53mm on the 1660
It will perform better in a small case as it will be an extra exhaust fan.
Out of curiosity, why do you want a blower / reference GPU style cooler instead of open air style?
Sorry, I missed that post.It will perform better in a small case as it will be an extra exhaust fan.
