Heatsink modding

[Scooby-Doo]

there is no reason to replace the thermal adhesive pads under the alum plate. My mod is averaging temperatures of 42 degrees with programs running and 38 degrees with no programs running. All I did was add 2 30x30x25 mm heat sinks and a 5 mm thermal pad. There is no reason to take off the aluminum plate covering the CPU as it can only lead to problems. You can read the post earlier from Loko. explaining this to me. My advice is to keep it simple. Good luck

You´re absolutely right. But there are guys, who have more problems with temperature despite of a good cooling design.
A good solution would be to install the heatsinks. If the cooling isn´t sufficient, one can change the cooling pads. I had no problems to put them in. And I gained a additive temperature reduction.
Everyone has to try, what is necessary for his machine. Temps around 50 ° C are absolutely o.k..
No one can say, what is necessary for his machine some guys had probelms with nthe ewer mainboard version.

A personal remark:
This machine is nice and cheap enough to play around. The ability of the cpu is very limited. E.g. with an android box (for the same price) there are much better results possible for example in VOD streaming. At least it´s a good energy saving office PC with some additional multimedia possibilities and good modding abilities.

I think I may have come off as being a little cocky, which I had no intent of doing. You are right, all mods are different and done for different reasons. I had the same plan as Vestiaz, until Loko said the pads may not be necessary to change and pointed that out to me and I was trying to point out the same thing. I followed your mod on mine so you obviously know more about this than me. Follow the instructions from scooby and you will be fine.

I changed the thermal pads on the CPU and stuff and also added extra for the RAM. Put on a bunch of heatsinks on the top.

I'm getting temperatures of about 70 at 95% load, and about 60 on 5% load. I still haven't put a heatsink on the underside so when that arrives I hope it will take off a few more degrees. So far this mod has been great though, thanks to everyone involved.

Note: don't get 15mm heatsinks, go for 12mm or so. The 15mm ends up getting in the way of the plastic at the top and you have to bend the circuit board to be able to screw it back in.

I am thinking which 5mm thermal pad to buy for the underside of the device. I don't want an extreme cooling mod, just the thermal pad for a quick and easy 5-10C drop.

I have found two sellers for it with significant difference in price.
This http://www.****.de/itm/121310218629 is 18.55 Euros including postage to Greece. The positive thing is that it states it is 5W/mK

This http://www.****.ca/itm/100mm-x100mm-...item3a9db1ad34 is just 7.15 Euros but it doesn't state it's thermal properties.

Any thoughts?

I re modded my pipo. I used artic silver 5 and coated the alum plate. Then added 2, 25 x 25 x 15 mm heatsinks. Added another peace of 5 mm thermal to power supply and voila. Under prime stress test here are the results Temps averaged around 53-55 Celsius after a half hour.

could you put pics about your modding please?

I find it very interesting and easy, and I want to do something easy, because I'm novice in modding.


Thanks

Yes of course. Included are pics of Temps while using prime with cpu at 100%, pics of windows at idle and pics of mod. Notice that I left space between the 5mm thermal pads for free air flow. I hope these pictures help. Good Luck!
I was unable to load pic of prime results. It is included in a previous post from me.

Thanks a lot!!

Although I though that it is better if there is no space between the 5 mm thermal pad and the case.....

[no_spam_for_me]

I think he talk about the space between the pads and not between pad and case....

Oh !

I think you are right, sorry....

Thanks for posting the pics. Where did you get your Heatsinks and Pads? Thanks in advance.

I purchased the heatsinks through ****, do a search for 25x25x15 mm heatsinks and you will find a range of heatsinks to pick from varying in price and size. Mine are 30x30x15 mm. Do not buy any larger than 15 mm in height, preferably 12 mm. The thermal pad I bought through amazon. It was 200x100x5 mm, then I cut it to fit. You will not need this much. You might be able to get away with 100x100x5 mm. I have about 40% left. Keep me posted on your results. Good Luck.

Yesterday I tried some heatsinks with the PCB out of case.

I think, the most important is the heatsink over the cpu, with one 37x37x30 mm the system goes perfect, temps never go to 70º. It can't be fixed because don't fit (with hole in case, could be)

With 12 mm heatsinks the system goes hot over 70º, almost 80º at stress tests. (No one better than play 20 minuntes of 1080 video with chrome, IE works smoothly)

I put 1 mm. thermal pad inside alu plate.

Today I hope do some more test for choose heatsinks.

EDIT: with picture of bottom case:



EDIT2: temperatures by playing 15 min vimeo video 1080 with 15 mm heatsink and closed case, by the way case goes hotter than without mod.

I found after testing that the 5 mm thick pad will drop the temperature the most. I believe this is critical for this mod to significantly lower the temperature. My mod becomes quite warm on the bottom due to the heat transfer from the large pad. Good luck.

You´re the next one with Mainboard version 1.3 with these temperature problems. Normally you mod will lower the temps under 50 ° or lower. This are the experiences af all the mods I viewed.
I´m very shure that there is a problem with that mainboard version. If the thermal pad on the meinboard backside doesn´t help you should think about air cooling.

Is possible that 1.3 mainboard get worst behavior than others?

After fix the adhesive and some pieces of thermal pad at bottom case, the temperature flow through the case keeping it very much warmer than without mod. So, it is working well, I supose It would be better with 5mm. quality thermal pad.

As far as I understand, there are two key points: heatsink over cpu and thermal pad at bottom case for good results.

Heatsink over memory is much cooler than cpu,s one.

I'll keep trying to getting better results
