No one tried to cooling the sxps16 SouthBridge?

Hi my friends.. by what i read about the critical heating in the sxps16, i see that the problem is caused by the SB..

So.. anyone tried to cooling that component? Only with cooling pad? can't do a heatsink maybe linked to the heatpipe?

I'm a dreamer???

thanks a lot

 

If you have a SXPS16 please take a photo and upload it here anything is possible.
How hot are these or your unit getting?

 

well.. i was misunderstood.. i'm not yet a sxps16 user.. but i read about it from last august..

Now.. one of the big trouble of this series.. is the heating while the system is stressed (videogame for sure.. and for strongest 3d applications..).

In the main thread many people say that the heating is located under the touchpad.. and the heat is so huge that can't use the TP..

Unded the TouchPad there's the SouthBridge.. the temp of the videocard and cpu wasn't so high.. so.. suppose that if we can cooling the sb.. the heating will reduce.. isn't it??

thanks a lot

 

Ok no problem I should think someone has done such a thing already.
Its not just the SB you have other components chipset, GPU, Ram, wireless cards, PSU where a fair amount of heat is being generated.
On paper these designs look good from Dell but in the real world they are well poor across the board of the range of laptops.
Dell need to rethink it's cooling designs as it not happening we should not need to be doing R&D work on Dell's behalf.

 

It's the southbridge that makes it a heat monster though, when you feel the back of the laptop (where the chipset, GPU and CPU are) it isn't too hot

 

Yeah, its the SB... hottest is the front/thinnest parts of the notebook.

 

so.. can WE fix it?? anyone tried to fix??

 

I would guess you woud have to drill a hole in the chasis to put a heat pipe through

 

I was initially going to open up my laptop and add a small heatsink to the SB to help it dissipate heat but then I decided against it last minute. The gains will probably be minimal and I don't really feel like cracking open a brand new notebook.

 

Adding a pssive heat sink to the southbridge will make no difference at all to the external temperatures, we need to get the heat kicked out of the fan where it is actually being cooled by cool air. Having a passive heat sink in an enclosed space just doesn't work, also the outside is heated up by the infrared radioation which is still in essentially the same place if you use a passive one, what we want is to use active cooling and have the energy kicked out the back

 

That's why I didn't bother, the passive heatsink would've had minimal impact. Active cooling isn't possible, the space is far too confined based on what I've seen in pictures. The best bet right now is to use a cooling pad.

 

Infrared what? I dont quite understand that sentance.

 

infrared radiation is basically a fancy name for heat waves

 

There isn't much you can do. The SB is located at the front of the system where it is the thinnest.

That area is a complete dead spot for airflow. If you can just wait for the next iteration of the 1640 (maybe 1645??)
