As I've decided to change my pump.. I'm thinking either the D5 or the DSP-MAG... The mag is tiny and cheaper than the D5. I don't know what the flow is and I'm changing tubing sizes from 1/2" to a bit smaller. I am also probably changing waterblock and getting rid of the heatercore for 2 80mm blackice's... So which pump do you guys think.
 
Depeding on your CPU block the MAG would probably give the better temps considering your small amount of radiator power. I doubt the extra flow the D5 would give could make up for the much larger heat dump.
 
Don't forget about the Laing DDC, especially since it's a native 3/8" ID part with excellent head pressure, but probably not as much flow as the Mag or D5.
 
The mag is just really appealing right now for its size... My current is an Eheim... I'm switching cause the issues with 1/2" and I don't think I'm going to loose that much in temps area but switching out some of the larger stuff. The proc is OC'd only like 500mhz right now...
 
the mag is also nice because you can use 1/2" OR 3/8" barbs on it.
+ its small and quiet and draws little power i could not be happyer with them due to the size/performance
 
I have a Mag and feel personally that it is an excellent pump. Not the most powerful mind you, but should be able to push over a gpm even with a restrictive block such as the storm.

Dead silence and size are the favored things about it.
 
I don't think the mag is going to get near a GPH through the Storm when you concider that the D% only pushes around 1.5 GPH through the Storm

"OK, I know many people will be asking: “How does it do with the Swiftech Storm waterblock?” To answer this question I have added a third flow test… :)

Pump (connected to reservoir) > 18” Tube > 6x6x2” heater core > 12” Tube > Swiftech Storm > 18” Tube > Graduated 5 gallon bottle."

Actually if you look at the other graphs on System cooling you can get a ballpark figure.

For instance Mag developes 2.8psi, or roughly 6.4 feet of head.
To push 1gpm through a Storm you need around 1.4psi.
At 1.4psi Mag pushes 1.3 to 1.4gpm

Add in hose restriction and what not and you should be very close to 1 gallon per minute of flow.
 
You might, I'll have to ask Lee why it was left off the more restrictive block tests. I wondered about that when I first read the review. There might be some other under lying reason.
 
I really could use a comparison to the ehiem though... I mean... I'm pretty sure the flowrate on that sucker is pretty high. I'm also going into a whitewater block. The other thing I'm curious is that I could also switch to a swifty pump... I just like the size of this pump.

Yeah, I wonder the same thing. He posted on Procooling that he simply did not test it, no reason given. He did say he suspects performance to be below an Eheim 1250.

That is about where my math puts it...
 
Hey Bio-Hazard, Lee updated the graph for the Storm block. Looks like the Mag pushes .94 gallons per minute. Just a touch under 1gpm...
