I crapped a little.

OK so I need some advice here..

Last night my chum from across the pond and I were playing Transformers in co op. It was all good, and we completed two decepticon sections. However, later last night when it had cooled down a chunk I decided I wanted to play some Fallout 3. I got about an hour in, and then out of nowhere my rig shut down. I thought "How rude !" and immediately turned it back on again. It posted, the windows logo came up and it shut down again. My first thought was "Oh god please don't tell me that Klevv ram is unstable". On the third try I decided that I would look inside the rig as it was starting.

Sure enough, no flow on the GPU loop. Touched the back of the Fury X - oucho. Red hot.

I grabbed the 20" floor standing fan and directed it into the rig and then investigated. My first gut feeling was "Oh god no please tell me the pump has not failed" as it's a nightmare in this rig. I took apart the side panel of the interior and disconnected the £5 Gelid fan controller I had running 7v and plugged it into a 12v fan wire feed and yay, SPINNY FLOW METER !

So basically the fan controller I was using has died, leading me to believe that maybe the pump was pulling more current than it could handle.

So, I need a way of dropping down the V/speed of the pump without spending an arm and a leg. I don't need it to look nice, or do anything spectacular, just stop it sounding like a bumbleee with the constant wishy washy sound because it's going so fast it's actually whipping up bubbles in there and sending them around the loop.

Ta.

That sucks man, sorry to hear about this issue.


What pump are you using and what type of power connection does it use? It is hard to recommend anything when we don't know what we are dealing with.

 

[BigDaddyKong]

Ouch, that does have a high pucker factor.

I really don't want to say it but the Fury X appears to be fine. No glitches, no artefacts. That could have quite easily cooked it tbh I'm just grateful it shut down.

The pump apparently pulls 4.9w, but when I took apart the fan controller it was clear to see that it had burnt up (it stinks for a start) and is made of the cheapest crap you can buy.

That's twice I've been burnt by a Gelid (pun factually correct). Last time it was a poorly wired cross wired 24 pin extension that burnt my board and PSU.

Maybe go hunting for a used D5? I know that isn't cheap, and you are the king of budget modding, but that pump is too important to cheap out on. Spend the $$$ and get a D5 IMO.

 

[Surfie]

Does your pump have a speed control? I've only ever used a d5, plugged into psu directly, and controlled with the speed controller under it...

Edit: and i agree with Bartacus 100%.

you shouldnt go cheap on a pump. Its the heart of your loop. Heart dies, everything can die along with it.

For your concerns though, perhaps think about a DDC e.g. MCP 35x with pwm connector. It will allow you to connect it directly to your CPU fan header and control it from there. It doesn't draw much amps. I ran 2 of them on my cpu fan and cpu opt header for years before upgrading. It also has outstanding head pressure. I had mine set to around 29% PWM. so whisper quiet and yet still maintaining 1GPM

If it were me, I would spend big on the pump, go cheap on everything else. (to an extent)

It isn't a cheap pump. It's an Alphacool DC-LT

I mean yeah it's small, but tbh not what I would call cheap. Cheap is £5 with plastic barbs lol. No it's a proper pump, I just need a way to feed it 7v. I certainly wouldn't put it on a mobo header if I'm being honest because I bought it used. It has already fried a £100 fan controller and temp monitor screen and volt meter. That wasn't the pump's fault though, rather the friggin idiot that tried to solder the wires back on with pigeon poo. I've since braided off all of the solder and resoldered it properly. Basically the live wire came off and met the ground. Everything on that molex line apart from my £10 pump died. The £10 pump has been running since last October pretty much 24/7 BTW, it's a fantastic pump.

How is it wired in fan connectors?

You can get different levels of fan speed reducer or you can get beefier rheobus adjusters (like a fan controller but they can handle a higher load)

Either that or just look for the fan controllers that can take more abuse. Its likely to have overheated.

I have a molex - 6 12v fan adapter hidden where the wiring goes. So right now I am using one of those. I was using one of those into the fan controller then off to the pump.

I need a smallish controller that I can hide. I don't think it should have overheated, because it was literally stuck to the rig on the intake holes about 2" from 120mm fan drawing air in. It's likely it was just crap like everything else Gelid make, which has kinda been confirmed by me taking it apart and seeing the cap and stuff they used. Awful tbh.


Also this. Dear god, please make my cleaned key caps dry faster so I can put my mech board back together and stop missing bloody letters all of the time.

 

[tinytomlogan]

Been a long time since Ive had anything to do with active controllers tbh. I know Noctua have just brought one out though. Maybe give that a look.

 

[AlienALX]

Well I have been told by an electronics expert (just now) that using the 7v trick actually puts less strain on the PSU than using a resistor etc.

So I will try that when I can be bothered to move (around 10pm when it cools down some).
