Cooling: Hanging a Kilo off your Motherboard?

Oh thanks... I think somebody pointed to TheITWares before. I'd forgotten.

Anyway, I think I'll get this cooler fitted first, now, even though my idea had been to minimise removals of the motherboard.

Using an "ordinary" PC, at the family place in Singapore (Acer, I think) made me realise just how quiet my machine is already!

Here's the old AMD stock cooler, compared to the new one

And here's the kilo actually hanging off the motherboard. Notice the wheels, too: this is a very useful upgrade as the PC now weighs 20kg. Being nylon, they also improve the sound when playing from CD --- although, of course, they have no effect when playing music from the HDD.

:cool:


With the twin fans controlled by the mb, it runs at around 700rpm, with one case fan on medium and one on low speed. If I load the processors to max, I have to increase the case fans to high speed. However, at 1,000-plus rpm there is still no whine like the AMD at 5,000.

So now, the case fans are the noisiest part of the machine :p
 
Know what's missing about the platform on wheels?

An outboard motor and rudder stick for steering!! :D

Dont forget to add the loudest horn you can find ;)

Cheers
 
I made one for the toolbox too :D

new idea: more fans and a skirt... make it a hovercraft! :lol:

The computer fits into a tight corner, and this platform has made it really easy to move in and out instead of a pain in the neck/back/everywhere. Even moving it a few inches to get at the back panel now takes no effort.

Did I mention that this final kilo has brought the total to twenty kg? :cool:
 
Nice congrats! Second pic is a bit too small to see though.

How are the temps now, expecially with our soaring summers? and is that an Antec CP series powersupply?
 
Yes, it is a CP-850. I embraced a non-standard! Only fits specified Antec cases --- but I would hope that the case and the psu will see me through at least one further generation of mb/cpu/etc combination, and I would expect to get three years out of each generation. If I don't, the Financial Director will be wanting to know why!

Important thing about the Antec PSU: it is silent. This might be because I am running at a fraction of its capacity.

The temperatures and the noise? Well, as mentioned, I need to get more air moving through that case, and will probably add two more fans at the front. I'd like to see the CPU cooler at less than its current 700-plus RPM, but there is really not much noise coming. Yesterday I was getting some odd sounds: harmonics, or maybe interference. Today that has gone. AMD CPU temperature 41 to 45. It is certainly reacting to the increase in ambient temperatures --- as am I!

I wonder if I put enough thermal compound. Everywhere I read advice to use very little, so I did. Anyway, if the unit wasn't cooling, the cpu would have fried by now.

One should only put enough thermal compound to fill in any microscopic gaps in contact between heatsink and cpu - because manufacturing tolerances may leave micron level uneven surface not visible to naked eye (or Ms Poonum :D)

Anything more is counterproductive. You may be better off smearing the thermal compound all over the body like a Naga sadhu covered from head to toe in holy ash - maybe it might help in this hot summer? :rolleyes: :D ok Kidding :)

I think the CP series could see you through the next 2-3 generations if you are lucky!

The recommended formula is using an amount similar to the size of a grain of rice. Which compound did you use ?
 
That little? Then I guess that I used enough. The instructions say something about 4mm circle; I think I put very slightly less. It doesn't say anything about spreading it, though, and neither did a couple of demo videos I watched on Youtube. I find it hard to believe that it would be squeezed all over --- but then, perhaps if I had inserted a finger before tightening the screws, I might have a different idea!

The installation was undramatic. Having removed all the mb connections, I started to wonder if I could fit it with the mb in the case. The backplate is not captive; if all four screws were undone, it would just fall off, but the stock plastic bracket is fairly flexible, and the screws are long enough to permit loosening them enough and, with a little gentle twisting of the plastic, to get the Noctua brackets screwed in, one end at a time, while the remaining screws hold the plate. Noctua's instruction to "tighten the screws until they stop," leaves no room to worry about overtightening.

Lining up in-case was probably harder, but not that hard.

Of the remaining grease, I'll start with three stripes on each arm and three on the forehead. If this works, I'll apply more elsewhere. Anything to reduce the summer AC bills! :lol:

(Actually, I think vibuti (sp?) does have some cooling effect!)
