Is PMP-450 equal to MCP655? Which is better: Koolance or Swiftech? - Page 3

Both are a Laing D5-38 Vario pump:

BTW, just noticed that "Laing-inc" the original website is now gone??? Looks to me like ownership may have changed or something...

Only difference is the Koolance version comes with the blue RPM wire installed.

In addition Swiftech includes some accessories in the box such as a neoprene vibration dampening pad and instructions.

I like having the RPM wire feature myself as an easy motherboard shut down, but I do also like getting the neoprene pad with the swiftech package.

Both manufacturers note voiding warranty with the top is modified although some have suggested that Koolance is a bit more forgiving although I've never had any experience to suggest either one is any better. I take the personal stance that if I modify a pump with a top that I'm going to own anything that happens which I would suggest as well. Aftermarket tops do stress the pump motor more than usual, so I think that's only fair.

Anyhow, the only one to avoid is the "Basic" or fixed speed model pump. Per the specs it's not very clear that it's a lower powered pump, when it's actually stuck at setting 4 which is quite a bit weaker than the setting 5.


I'm more curious as to what may or may not change if the old "Laing" is now owned by someone else..It's a good thing I have about a dozen spare pumps lying around...biggrin.gif

desg, They're the exact same pump.. Both manufactured by Laing so it does not matter which pump you buy, They're exactly the same, apart from the fact the koolance has the rpm wire..

Not sure how many times you need to ask.. BUT THEY'RE THE SAME!

AIDA64 has a alert setting where you can set it to shutdown if a fan/pump rpm goes below a set RPM. Only downside is that AID64 isn't free.
