Heatsink mod! Must read it if you use Fan control!

That's awesome. Has everyone else experienced this? Or is it pretty specific to that particular heatsink?

 

no, the high frequencies are still there with my mod...
But I am using aa1ctl

 

Yes, applying the heatsink the noise is lower.

 

now look at that...
I want something like that too...

matrix321:Nice... Where to find that particular heat sink u.s.? thanks if you can post linkthat would be great. thank-u.

Hmm a lil off topic but yet temperature related. I just noticed viewing a lot of pics and comparing them to my Acer 150 6cell Onyx Black model, I dont have a vent on the bottom where the fan suppose to take in air. Maybe that is why some complain about fan noise, and mine is so quiet even without this mod.

Anyway I got some heatsinks off ebay and will try this. My acer doesnt get hot but I'm opening it to install more ram and installing bluetooth so why not lol. My Acer runs 53*C after 12hours at 45% cpu doing skype video. Yes I leave skype on haha . Will see what happens after.

 

I don't think this piece of metal do anything all all but I could be wrong...
One must understand how a heatsink works, the heigh of the fins, the spacing and material used.

Anyone can custom make one and stamp it as a heatsink

 

To my knowledge there is no vent on the One. I've seen the prototypes with vents, but not any production models. I don't understand why they decided to omit it in the production models.

 

where should it be?
can you post a picture - or change an existing picture?

 

I got some ram-sinks off ebay for a few dollars. Picked up an aluminum sign from a hardware store. You know the ones that show a msg like "no smoking" or "beware of dogs" lol. These are great because they are aluminum and the other side has adhesive. I did not put the adhesive side down onto the heatsink because that would collect dust in the duct, I put it up. The reason for this is for aditional adhesive strength when you tape the sides to seal the duct.

These ram-sinks are tiny with a high of 5.5mm. If you were to put a flat aluminum cover like I did, the cover would actually touch the top of the heatsink. However if you dont plan to put a cover, you have much more room to work with. 7-8mm heatsinks are definitely good without a cover. Notice I bent my cover to allow more airflow to glide over the heatsinks aswell. These heatsinks are a perfect fit if you want to put them side by side across the width of cooler, however I decided to put one behind the other. The reason for this is the heatsinks will also restrict airflow, and I dont want to hinder the origonal design of this cooler aswell so airflow with this method should not be an issue.

I had no real reason to do this mod, but I like playing around . I dont use my AspireOne for anything very cpu intensive. I use Skype a lot, which uses usually 50-60% cpu. At that speed the notebook is at 57*C after several hours. Not a big deal, but I was planning to crack my notebook open to install more ram and a bluetooth dongle (other post regarding additional usb port) and I thought I might aswell do this.

So my result is as follows:

Stock:
IDLE: 37*C
SKYPE (50% cpu): 57*C

Modded:
IDLE: 34*C
SKYPE (50% cpu): 47*C

The fan speed is considerably slower. At idle no difference, but using skype the fan usually speeds up but after the mod it does not and remains quiet. I am not using any fan software, and my bios is 3304 as it came stock with my A150 AspireOne. Here are some pix of my mod: (sorry for the order, the attachments show in reverse lol)

 

nice.. i am going to put this into my AAO-150.

want to add that i am now running tiny vista v2, and that it runs considerably cooler than what it did with the bloated WinXP provided by Acer. (I have been using AA1FanControl with both OS's)

 

In this weekend i cut a hole in the bottom of my AA1 A150, installed a better fan, filled up the heatsink with cupper heatsinks, applied noctua thermal grease instead of the blue pads, and installed a "fan shield" - dunno what to call it, but a wire thing that protects the fan and makes sures nothing can come through the hole i the bottom of the aao.

Now getting temperatures around 55deg after hours of stress with fanspeed at low, if i just use it normally for surf etc the fan will barely start up.

Will add pictures later

 

rt82,

I used the same ram heatsinks as you did, but I put 6 packed together in the channel. You were correct, that config hampers the total airflow. My wireless card & hdd heated up cuz of the lack of negative air flow. I switched to your example of the single row of heatsinks and i put 3 in the center. Now the whole unit runs cooler. My avg after an hour of idling is 45deg C, but I am not using a throttle on the cpu, nor fan control. Mine is set to run 1.6Ghz all the time for performance, not battery life. It doesn't get hotter than 60deg C running 100% loaded.

 

I am interested in seeing how this is done. As to my previous post, did you take into account the cooling of the other hardware? the stock fan is designed to create negative air flow to draw in air over the wireless card & hdd. Cutting a hole for a more direct access for cpu cooling may not be good for the other devices.

 

where can I order the thermal pad just like the one for this heatsink? the other one's I've bought were way too thin, this is a bit more thicker than the other ones. I kinda ripped my thermal pad when I removed the heatsink :O

 

I don't know where u can get the exact black tape, but this looks like it has the right thickness:

If u want a permanent fix, look for Arctic Silver 2-part thermal epoxy.

 

Hello guys,

I just want to give my experience with the fan mod. Well, I tried to put thermal paste under the original heatsink. At first it was no problem at all, but the temperatures were even higher than before. The problem was that the heatsink was not 100% even and there was a little gap over the chipset. I carefully tried to bend it and reapply the paste about 10 times. It took me hours to get it to a point where both chips are touching and the temperature was just like before. It was really a pain. :evil: I guess that's why they use these soft pads.

So my advice to you is: Only put some grease under the heatsink if you could deal with that problem. I really can not recommend it and maybe it's not even worth the hassle.

 

I took out the small thermal pad on the chipset and cpu and replaced it with regular thermal paste too.

I bent the heatsink and it seems to make good contact but the bottom of the aa1 gets SUPER hot now after some zsnes zelda (playing on my lap), I am not sure if it is because the heat is dissipating better away from the cpu/chipset and into the chassis, or if there is a problem.

My new heatsink had to be sanded down to make it fit, it does touch the bottom of the case, in fact it is held there quite securely.

I am thinking the bending of the stock heatsink, and the addition of a larger heatsink pressing the original one down, will hold the stuff close enough that they should touch. Hoping it does anyways


I am tempted to insert a aluminum spacer (pop can) but I don't know if if will help.

What would be an normal temp for the bottom of the case under heavy load?
