Internal cooling mod on a Vaio?

[Rob_B]

My Vaio gets quite warm (but not hot) undeneath in the area around the GPU heatsink (big silver thing in this pic)



I fancy adding some kind of additional cooling here, no real reason other than to mod it a bit! I was thinking of a really low profile fan (like an old 486 cooler on low volts) or somehow linking the HS to the CPU HSF (copper bar & fan as in the pic) any ideas?

Rest of the laptop internals can be seen here FS CPU/HDD Upgrade Guide (Pics) - Page 2 - Notebook Forums and Laptop Discussion

Thanks for any help guys!

One thing quite a few people do is to replace the thermal compound with something like AS5, it can knock around 10 degrees off some laptops.

Interestingly, when I pulled off the heatsink from my laptop, a thin layer of silvery metal (Probably nickel?) got stuck on the CPU surface :S Probably because of that, my CPU temp went down for like 2'C only.

Actually, after looking closer to the picture, I could suggest the following

If you have access to the equipment (like a milling machine), you could probably custom make a CPU-GPU heatsink block to replace the existing blocks.

I reckon that'll take 6~12 hours from drawing board to complete

I thought about replacing the large HS but dont have the skill or equipment, already replaced the CPU paste with some MX2

The Large HS covers the GPU & another chip (not sure what but its not the CPU) but its slightly raised so there is a blue foamy stuff (like on GFX card RAM modules covered by a big cooler) I don't think it makes contact if you dont have this as tried some MX2 but it left very little on the chips when I installed/removed it to check contact.

Im not after a cooling base, I realise I could get one but fancy something a bit more bespoke!

That is the northbridge with the integrated graphics. Since the graphics portion is switched off, it shouldn't generate much heat. That small bit of contact is probably good enough, assuming those MX2 don't just slide off the heatsink when you move around

You probably won't be able to find something that you could do a straight swap in. With that much of a height restriction your best bet still lies with the cooling base.
Without any equipment even if you find the right piece you can't drill the required holes to fit

[Rob_B]

The gap it too much, I've added a bit of MX2 to the foamy stuff to fill in an holes to improve the contact, not much more I can do

Tried an old NB HS inside but the case desn't close properley around it, think I might just leave it & perhaps upgrade the CPU at some point!
