Laptop Chipset Temperature

[mclaren85]

I have a Sony Vaio (2012), which has i7-3632qm processor with 8gb ram on HM76 chipset. When I look the idle temperatures with Aida and hwinfo64, the PCH temperatures are reads as 63-64 degress Celsius.. When I take a look at the inside, there is no HS or thermal pad on the HM76 southbridge. Do you think it is normal for a laptop? Should I put a thermal pad and a small Hs on it or only thermal pad would be enough for cooling the chipset?
Regards,

,

I've found this small hs. Does it work?

 

[mclaren85]

Will try this piece and share the results.

or only thermal pad would be enough for cooling the chipset?

Why would you think only a thermal pad would be a good idea? Have you done any research to learn what thermal pads are intended for?

Why would you think covering up the device would be a good thing?

Thermal pads, like thermal paste and other TIMs (thermal interface materials) are used to fill the tiny microscopic pits and valleys of the mating surfaces between the device AND its heatsink.

Thermal pads are NOT as efficient as thermal pastes and are intended to be used where pastes are not practical.

TIMs do NOT extract (or "sink") heat. They just prevent insulating air from getting trapped between the device and its heatsink, and provide a path for the heat to move through those now filled microscopic gaps.

IF AND ONLY IF there is room for a heatsink to be mounted on that device too should you use a thermal pad (though I would use adhesive paste) and that is AS LONG AS there is also clearance for the laptop's fan to move air through the heatsink too.

My best advice, and one I really hope you heed is to "just leave it alone!"

Yes you are right so I put a small heatsink. Now it is working 5-6 degree celsius cooler.

So I think using thermal pads solely act as an insulator rather than dissipator.

Exactly. You don't want an insulator - essentially a blanket - on top of the device.

i am always fascinated by your obsession with chipsets.

Save up some money and get A/C, all hardware temps go down!...

You are definitely right but it seems that laptop chipset has cooled down to 53 degree after the small modification.

No it's my old laptop Bought in 2012.. I didn't bother installing windows 10 or 11 on it

That video explains it well

I think it is most fragile part for defining the longevity of the system

during this hot summer times, I touch the HS surface and nearly instantly the temp goes down. I don't know why manufacturers not think of putting an extra fan to cool down the chipset? I know the price will rise but how much? 5 dollars maybe?

Interesting take.

I try to harden my equipment to heat (by using top grade capacitors) so I can save money by not using AC which is very expensive to run.

Temps seem normal. If you're concerned, you can always add a cooling pad.
I like the ones from Deepcool.

Cost/Benefit.

That PCH is probably to work at 90 degress. so it being at 63 means it still has plenty of head room and the extra cost in making a duct/heatsink/fan etc for 0 performance benefit is how companies see things.

 

[Bill_Bright]

I don't know why manufacturers not think of putting an extra fan to cool down the chipset?

Because it is not needed.

Years ago, chipsets always had a little 40mm box fan on them. But those fans were and still are cheap (in quality), they are very noisy (especially after the bearings started to wear) and they failed soon and regularly.

This was also when case cooling often consisted of the fan in the PSU and maybe one little 80mm case fan.

After constant failures, they went to adding a slightly bigger heat sink only instead of a 40mm fan on a small heatsink - this as case cooling improved too. Finally CPUs started integrating the Northbridge ICs into the CPUs and the Southbridges didn't (and don't) need additional cooling - other than what case cooling provides.

I say, stop trying to fix things that are not broken. If you think your chip set temperature is too high, address better case cooling, cable management, and air flow.

I already have it made by Microsoft. Not sure if it's working as intended though

well I directed an Arctic fan running at half speed to the PCH. Temps lowered about 13 degree Celsius. Wouvv!

 

[Ruru]

Nothing special here. Even some prebuilt desktops have their chipsets naked. They do run warm, but they are fine without a heatsink, yet I still wonder that is it worth of saving few cents to not have a heatsink..

 

[mclaren85]

Unfortunately there is no way to add more fans to a laptop

Nah, a chipset won't need a fan, but like I posted above, being totally without any cooling is just stupid for a few cents saving in the manufacturing costs..

Totally agree. Failing chipset is a real thing and manufacturers should take care as they do for GPU and CPU.

Without A/C in a hot climate there's only so much you can do....

It is not "totally without any cooling". Come on you guys! Some common sense needs to come into play here!

Are these chips encased in a sealed, insulated box! No! They are essentially out in the open where heat can simply radiate off and away from the chip. But is that all? NO! The laptop's cooling fan(s) is moving air through case to move that radiated heat out of the area too.

Would it make even a tiny bit of sense for ASUS, Dell, Acer, HP, Lenovo, Samsung, MSI, Apple and others to leave those chips "without any cooling"? Of course not. Would it make even a tiny bit of sense for those companies to leave those chips vulnerable to overheating when it costs so little to add additional cooling hardware? No, of course not.

Do you really think the electrical engineers and motherboard designers at those companies are stupid? Do you really think you are smarter then all of them?

Time to get real here, folks and face reality. You are not smarter than all those companies. Stop trying to fix things that are not broken.

No we're not better any of them but I'm sure planned obsolescence thing has played role here. I'm also pretty sure the chipset without cooling system would not die instantly but the life expectancy definitely decreases.
Just please take a look my laptops mainboard and modded chipset. It has nothing to do with the cooling fan. After my modification, nothing harmed but temperature of the chipset decreased, which is a preferable solution isn't it?

What thermal glue did you use?
