Im sorry,but PWM only means something if you turn your pumps up and down...seeing as most D5's are silent,there is no need to turn them down,its a worthless feature.

The reason the DDC has PWM is that if it runs for too long flatout,it burns up.

If you think pwm is useless then you are using it wrong. Pwm capable fans and pumps are able to run at significantly lower speeds than voltage controlled variants. Plus you don't need to risk blowing up a fan control to slow down the pump.

The ddc is a prefectly reliable pump if you use it correctly. But most noobs don't. Everyone seems to think you need ridiculous amounts of flow in a loop these days, but you don't. Either slow the pump down or build a more restrictive loop and a ddc will last damn near forever. I've been using only ddcs now for 8 years. I've had none die that wasn't caused by my own mistakes.

This is completely true. I've heard you say that flowrate is over rated a few times but didn't know just how true that is. I can turn my pumps down to speeds much lower than I thought that I should be able to without effecting temps and I would think that my loop is very restrictive. I'm sure that I could have stuck with a single 355 and been fine.

I wish i could say the same....I have had 2 dead DDC's on 2 different loops,not a happytime.

As long as im over 1Gpm,thats all i ask...although,again,i see no advantage to slowing pumps down,PWM or not. PWM for fans? Yes,very handy. PWM for pumps? Not so much,not for me anyway....

Noobs dont cause burning pumps,thats a design flaw,so much so that HS kits are around for them...name another pump that requires that?

My only exception for the dislike of the DDC is for the 10w one,i still have mine and have had for some time,makes a nice flush pump and has been rock solid.

D5's all the way.

Love those brush-less pumps so much I bought a RD-20, and I absolutely love it. Just a little louder than a D5 but who cares, 18m head!! biggrin.gif

Owned one MCP35x (GF's puter), five D5's and an RD-20. The MCP35x was a pain in the butt to get silent. I also had some issues on the pump with the 12v lead to molex, shoddy workmanship or bad Q.A. had me soldering the wires properly on a brand new pump. That and you need to get your profile setup with the PWM or that thing runs full tilt on the 12v molex, not fun when you're watching a movie and you can hear the pump running. Something the D5 has no problem with even at the highest speed or a 24v source.

I was considering a RD-30 for my SR2,then my mate on RRT showed me his Iwaki forcing d-plugs apart....i dont need that kind of push...thats almost childbearing amount of push!

Anecdote: First time I plugged it in I had 7/16 over 1/2 barb tubes and no zip ties. Safe to say things got wet.

It is a little noisy as far as pumps go (even when properly bled), so a good decoupling with some sound dampening material is sound advice; more so if you have it sitting in the computer case next to you. And RD-20 or RD30 is too much pump for one computer (no matter how much you argue) anyhow. But I needed it for a special application, and boy does it exceed the requirements I had set. It also dumps 60w of heat into the loop, so you almost need to plan an extra 120.1 to account for the extra heat dump. Meh, I had enough... tongue.gif

At best the pump change might give you .7 gpm or something along those lines, so don't expect any large gains. Generally if it flows and air isn't getting stuck in big pockets, I would call that success on pumping. You are better off spending you money on better fans or another radiator to add to the loop.
Whatever you do, just dont expect several degrees with a pump upgrade..you will be dissappointed.
Also electronic flow meters should be calibrated for accurancy. I have seen them off by 30% or more by simple things like different barbs or an elbow...don't trust the number unless the meter was calibrated.
