Title: The Dell XPS 15 9570 might inherit the same throttling issues as its predecessor
Post by: Redaktion on May 13, 2018, 11:03:34
The service manual for the Dell XPS 15 9570 has been posted online and it looks like the notebook will sport a similar heatsink design with 2 heat pipes as its predecessor. This raises concerns about the possible throttling issues as the previous XPS 15 9560 had to be undervolted and thermal pads applied to the VRMs in order to prevent performance drops due to thermal throttling and power limits.

Appears to have the same lousy cooling heatsink design with no active or passive vrm cooling. Similar laptops with a similar motherboard design almost always have vrm cooling built into the heatsink.

Check out my 9560 and the pursuit I've gone to eliminating throttling and improving cooling. Search Flickr for Dell xps 9560 heatsink or cooling.

For starters using clu would be a huge improvement for temperatures.

Thanks for this info. May I ask if you tried contacting Dell about it and what's their feedback please ?

Hi seiferflo,
We could do that but first we'd like to test drive the unit ourselves. There could be other changes under the hood and in software that might result in lesser throttling. Once we have good data we will get to know Dell's intentions behind this decision.
Title: Cooling pads / OPolar?
Post by: SIMON WEAVER on May 14, 2018, 19:35:00
I recently discovered the OPolar cooling fan that attaches to the side of my HP Envy 17 and seems to be doing a pretty good job keeping it a lot cooler.

How much do product like the OPolar, or a traditional cooling mat help reduce throttling. Would be very interested to see tests from someone who knows what they're doing.

I'm looking for an i9 processor but don't need a gaming GPU - so no need for a massive gaming laptop (with effective cooling). This leaves me concerned that the thinner laptops with i9 may just be throttled all the time - and most likely not even have overclocking enabled in the first place.

So that leaves something like the upcoming HP Zbook which is thicker and probably better coolec?

Here is the answer from Frank Azor's Twitter in response to a question regarding the cooling solution. It's a bit of an indirect answer but based on this, what we've seen with the service manual, and the history of 9550/9560, it's more of the same. I apologize for not hyper-linking but my account doesn't have enough posts yet.

@AzorFrank hey!! a lot of people are wondering about the cooling on the new dell xps. i know many are concerned that a hotter chip needs new cooling. any info would be awesome! I ordered a maxed out i9! can't wait to use it for music production :)

@AzorFrank

Replying to @ds_sec1 @rlytyvm
XPS 15 is not designed to run CPU and GPU simultaneously at 100% of their capacity.  It power and thermal shares between them depending on the task at hand.

Good info! Does keep me from buying the laptop for now.. Any idea when a full review off the 9570 will be up?

It HAS, just see the reddit post of today on the 9570. Who falls for Franks lies anyway?

Basically nothing has changed, not sure what's going on with the right side though.
