laing d5 pump speed

by most people's recommendation's i think it's 3.

also depends on what your cooling...ie...cpu,gpu,motherboard.

for just the cpu and gpu i think 3 is fine.
 
I found 5 too fast for bleeding as the water in the res is just too active to allow the air to rise properly.

What I meant is use 5 at the stage where you need to get the air out of rads without being able to tip the case, then keep nudgin I down until 3:)
 
Agree with cleeecooo - the extra omph is really helpful when filling/bleeding the loop (I usually pulse it between 3-5, them take it down to 1 as my res is only 150ml)

Day to day I use 2 but with a Ek x-top.

linky to my testing from a while back.

Green I would class as quiet - orange can be masked with fan noise - red, not acceptable imho (but my pc at the time was fanless)

Run mine on 2 also and that is through cpu gpu and two rads. Tried turning it higher and noise increased as did flow rate but didn't see any great differences in temp so turned it back down to keep it quiet.

found 5 to be opretty quiet aswell.

is this with a top?
 
found 5 helped blleding with my dual res, but use 3 for both pumps.

one thing ive always wondered is it ok to switch speeds while the pumps are running?

I've always done so

Same, but only when it's on a soft surface. On a hard desk it sounds awfull. Like being on a bus when it's stopped in traffic.

Yeah, I have the EK top (version 2 I think.) It is only a slight hum I get on 5 so it isn't noisey at all on 5, just noisier than on 2 and as my temps don't differ why run it on 5.

Oh ok, fair enough :)
 
I've always ran mine on 5
Can't hear the difference over PSU and 5 HDD's anyway.

Will it shorten the life running on 5?
Are there any benefits of decreasing it?
Running it through 2 GPU's, CPU and 2 rads
 
Surely flow rate wouldn't make a massive difference.
Going through the blocks slower is cancelled out as it travels through the rad slower
Going through the blocks faster is cancelled out as it travels through the rad quicker.

Obviously within reason, or am I wrong..?

if it goes though the blocks slower, then it has more time to take the heat in. As it goes slower through the rads, there's more time to disperse that heat. Obviously, if it spends too much time in the block, it will heat up too much

no, just doesn't picj up enough heat from the CPU and doesn't disperse much at the rad either.

Basically, you need to find a perfect balance
