Heatsink modding

[CRi]

I think it's the other way around. The lower value the better heat dissipation. Because i was asking myself why all the heatsinks with lower value were more expensive than the ones with higher value. And the value points to the resistance. Lesser resistance the heat "flows" trough > more resistance slower heat dissipation.

But i'm not a scientist, only my thoughts.

Nope, its the other way around.
The higher the number, the more conductive the material is (as opposed to resistive like described) :-)

Today i have run prime95 and stress tested the pipo. After 1,5 hours my temps was around 70 degres. My max was 72 on two cores and 75 on two cores. When i stopped the test the temps came down very fast.
I am really happy about this box.

Is your box modded or unmodded?

IT is modded. Before i had temps around 80-85 after 5 min.
Normal use the temp is around 60.

Nice, I just wanted to check.

At heatsink I'm also not the expert but if you talk about the 'R(th) K/W' I think you are right that lower is better because it seems to describe how much Kelvin hotter will it be per 1 Watt "power dissipation" so I think lower is better because I think it means that it is better able to absorb and transport the heat away... BUT I'm definitely not sure about this but it sounds sensible

Here an example
6 mm high http://www.conrad.de/ce/de/product/1...65-KW?ref=list (16,5)
vs.
10 mm high http://www.conrad.de/ce/de/product/1...57-KW?ref=list (15,7)



But at pad and paste they talk about W/mK and here higher is better...

Just finished up modding my box similar to how Scoob did his, I may take pictures in the next couple of days here. I need to swap out the heatsinks for ones shorter than 15mm, the main board doesn't 100% fit, but I've got some great results.

When playing flash videos, my CPU would get just under 80C, now full screen flash barely gets me to 60C. I used 5W/mK 1mm thick pad under the ALU plate over RAM, CPU and power; 12x25x15mm aluminum heatsinks (though like I said I'd go with slightly shorter ones if you're looking to order new); and 3.2W/mK 5mm thick pad underneath board in contact with bottom of the case.

Does anyone know the best way to maybe remove some of the plastic that's on the inside top of the case? I'd like to avoid buying new heatsinks if possible.

:
These hetsinks are a little bit to high, so that the meinboard bends alittle bit. everything functions, but it would be better to use heatsinks with a maximum height of 13 mm.

In my system the function. but if you take any other heatsink its okay. If you put them, or one big cooler over the complete alu plate or dirctly on the chips a height about 13 mm will fit better. the plastic part that holds the mainboard limits the height of the coolers.

Maybe two like this ones:

or maybe like this ones:

or these:

maybe 14mm is also too high but

Thanks for the suggestions, but I found http://www.****.com/itm/371219081414 shipping from USA for relatively cheap, and pre-adhesive'd.

At the end you have to decide by yourself, but the preadhesive heatsinks often have low quality. The adhesive properties of them are mostly very poor.

Trashed an old servers cool block

Its 1.5cm high. Il try to work it inside the box

So happy !

Hi guys (and ladies),

i'm happy to say i've resolved all my temperatures trouble with your kind advices. A special thank's to ScoobyDoo ^^

No more talk, just pictures :




And the CPU temperature and now 45 degrees when they were at 85 degrees in the same time.


And after 4 hours of stress, the CPU never go up to 70 degrees, excellent !

Used only 3 tools :
One thermal pad : http://www.amazon.fr/gp/product/B0051C287K
thermal adhesive : http://www.amazon.fr/gp/product/B006WXOV7W
heatskins : http://www.amazon.fr/gp/product/B008LZO3NQ

It´s so easy to mod, thanks for reproduction of my mods.

Looks like my coolblock was way too big.
i stuck some old copper from a laptop inside. Still
not perfect i got till max 77c but not higher.at least the cpu
doesnt throttle anymore

What do I use to check temp??
