New user to LIQUID cooling - Coolermaster LIQUID LITE 120

mclingo

Hi, Coolermaster LIQUID LITE 120 is a great budget cooler, at £35 its a bargain, however due to a fault on my mainboard I have only two headers working, a 4 pin CPU header which the main PWM fan is connected to and a 3 pin case fan which I have the pump connected to right now, the pump only has 3 pins.

I need the 3 pin header really to control my case fans so I want to know if its ok to Tee off my CPU header with a 4 pin to 3 pin converter and use that to power both the PWN fan and the pump.

I've also posted this on the coolermaster forum but its go so few posts on there I'm not holding out any hope, it doesnt look like coolermaster are active in these forums either, userless.

There will be a conflict in the bios. I think you will need something like this:

so i need yp connect the pump to the same header as the cpu?

Bigfingers

You can connect the pump to a 3 pin if you have to and turn the Bios monitoring off, otherwise a warning will come up. You can always adjust the pump speed through the coolermaster software.

So you can buy one of those adapters, connect it to the PWM and connect pump and fans to that.

hi, thanks again for your input, i could not find any software for the liquid lite version, the pump has a thee pin header so voltage only control?

Bigfingers

Ok well thats fine then, just plug the splitter into the 4 pin header and connect your fans and pump to the 3 pin outputs.

Cheers.

i ended up buying a refurb MB to replace this faulty one, has two 3 pin headers down, suspect some of the caps have gone. ive got the LIQUID cool raditor fan and the pump running off the PWN header and 5x 5v case fans running off one 3 pin header, this cant be good.

I'm also only achieving an average of 45 degrees on zero load that that isnt good either, however it never goes above 60 degrees on full load so it must be doing its job I guess.

This weather wont be helping in the UK

ok got the new mainboard hooked up but getting some disapointed figures maybe, 75 degrees at full load, seems a little high, cant work out if my pump is working properly either.

I have the radiator fan set up on the 4 pin PWN CPU header and the pump running off the PWR 3 pin header but I cant find out which fan is which to guage the RPM, no monitor tool I can find matches up with the description on the motherboard, PWR fan isnt even in the BIOS.

any idea what RPM the pump should be running at?

Bigfingers

I dont know what cpu you have, but with that cooler I would expect those figures to be normal. The pump should be powered off a 4 pin header. A lot of motherboards now come with the extra pump header.

Hi, the pump is a 3 pin variety, I had a 95 watt  i7 2700k in it but i swapped it out for a 65 watt low power i5 2400 hoping that would be cooler, dont think it is.

Through a process of elimination i've worked out which fan is doing what, i'm using argus monitor to control them, the pump is showing RPM of 2200  but is silent.

cpu idles about 40, max load is just about 75, this probably isnt bad to be honest, when I said max load I had my CPU running at 100% for 30 mins and my GPU about 80% at the same time so there was plenty of heat in the case.
