Strong magnets to prop up a reservoir/pump combo

Inspired by GFFEvents who did it on one of their builds, was to hide the pump res in the PSU chamber away from the motherboard chamber in the LL Evo RGB.

I did the same with mine, which would feel a little less cramped than it already is, but i forgot my D5 is a Vario (prefer those to PWM)... and because of the way its mounted (screwed through the case behind the mb tray, its almost impossible to reach the dial.

I wonder if there are magnets out there which i can use to attach the res to the holder? Would Neodymium magnets be strong enough?

Have taken magnets out old hard drives before
Very strong
Sort of a crescent shape and quite thin
Being thin and flat with a large surface area
Makes them quite useful

Though not sure about putting them too close
To a pump
Don't pumps work by magnetic field?
Electricity through copper windings to turn impellers?
 
Pumps do use magentic impellers so I would approach this method with caution. I dont think a D5 uses such an impeller however, I think they are directly driven.

Moving atrong magnets arpund near other components could be risk also.

ahh good point.. maybe magnets may not be the best idea then.. especially if its behind the mobo too.. guess another alternative could be to use door brackets

My pump/res combo just sits on top of my PSU in the side of my 011D Evo. The PC isn't exactly jumping about or didn't see any need to fix it in place. Also tubing prevents any significant movement.
 
Velcro, stuck down with Gorilla Glue.
ahh good ol' velcro, that could work actually. I'm hesitant with any type of glue though as i prefer not the leave any stains/residue should i come to sell the res later on down the line.. basically a less destructive way of doing things

Yeah.. i'm not overly concerned about this, it just makes it look tidier in a way, but easily removable so i can adjust the dial at the back if needed. Even if the XL is big, there isn't actually a lot of room for the flat res combo on the PSU side.

Velcro cable ties with neodymium magnets gorilla glued to them. Leave nothing to chance.

Neodymium magnets would easily be strong enough. They are usually sold by dimension 20x4mm eg.

Fits perfectly on top of the PSU and I can reach the dial on the D5 to adjust the speed with a screwdriver through the holes at the rear of the case :)

Yeah i purchased a set last night to play around with and to see if it would fit my needs. I bought the ones which have a steel cap on them 20x4 i think.. but it seems to lose its magnetism with the cap on. (worse than a weak fridge magnet)

My idea was to screw one magnet to the holder and another to the res like this. Ignore the countersunk screws, i have some countersunk m4 bolts which should be flat enough

Ooo i'll look into that. Does the res have any mounting holes to bolt onto the case.. or is it just freestanding. Any holders for it?

Actually just checked I have the previous version which has a piece of acrylic that extends out under the pump, not sure why they have changed that. My version can be screwed down if you wanted to but look like the new version comes with velcro to attach.
 
Looking at how the bracket fixes to the motherboard plate I reckon you could get away with three of the four mounting screws being bare without nuts leaving say the top right one being the one you leave a nut on, or even a wingnut if it will fit, to tighten it up, it wouldn't go anywhere even if was only tightened down on one nut. By this I mean you put four short m4 set screws through the mobo, with a nut on each to fix them all to the mobo, then put your bracket of on the excess thread sticking out to locate everything, then just have a single other nut on one of these to then tighten it down.

Setscrew[]mobo[]nut[]bracket for the 3 ones just used for locating. Setscrew[]mobo[]nut[]bracket[]nut for the one used for tightening.

edit: of course, whatever method you use, you then find it vibrates like buggery and then have to go back to square one :D Then that velcro will look even more tempting as it will effectively de-couple it from the mobo plate..

i think i know what you mean.. i did try something similar to that, but decided against it due to as you say vibrations.

The way it's currently been setup at the moment (till i upgrade soon that is),

screw > mb > D5 rear hole > nut > D5 front hole > res

The nut is situated where it is to essentially stop the screw from wobbling.

The holder itself can stay as is.. i'll just use shorter screws like 15mm to attach to the mb plate.. but i kinda want to make the res like a quick release function where it would easily just pop off the holder... but that again assumes i will be using soft tubing. It would be impossible to do this if i was running hard line unless i used those rotation fittings from Granzon.

Edit: That could actually work.. 4 small screws to mount holder to mb tray. 2 velco straps to secure the top of the res to the top section of the holder. a thin door bracket to hold the bottom of the res (like a fold down table), then use Grandzon fittins like these which will allow me to use hard tubing to the res

D5 impeller floats on a bearing immersed in the fluid, and the electromagnet coils surround it. Same as a DDC, just different proportions really.

Couldn't you just add a potentiometer
To the pumps power wire?
To make controlling it more accessible?
Would need to be a high power potentiometer as it's burning off some of the excess power not used by the pump. Could probably wire out the vario selector to a little dial/rotary switch though....

Pretty sure aranging them like this is the wrong way to use them.
You should screw to metal plate to one side and the magnet to the other.
