*** Official Clevo P870DM2/P870DM3 (Sager NP9873/NP9872) Owner's Lounge! - The Phoenix 2 is here! **

I emailed my contact at XoticPC. Hopefully I will hear back about this tomorrow. I knew something was off with this singular heatsink. T-Heatsink makes so much more sense for the 1080 at the very least.

If they tell me otherwise, I don't know how to proceed. Is it possible/easy to purchase the heatstink easily elsewhere, or should I return it and just get an SLI rig or buy elsewhere? Hm...

 

Looks like the T heatsink to me. Six heat pipes and fins on both fans.

 

At least you have a grill connected to your second fan. Mine is completely disconnected from the heat solution.

EDIT: Nah, you have the T-shaped one, it seems.

 

Yep, it's the t-shaped one!

 

And that's the one I need, because those loggerheads have given me the 1070-specific single fan sink.

 

I have the vapor chamber heatsink with a single 1080 and the temps are great, never going above 76c while gaming. I have the fans set to automatic and they don't go above 2300 rpm. I have removed the heat sink to see what the fit is like and it's very good.

You're quite right. I overthought it and took it apart again to look at it. That's what worried and tired curiosity will get you, haha. I was worried about the heat so I overthought it after the heatsink discussion came up.

Now getting the vapor heatsink would be awesome.

 

I don't have the money for a vapor upgrade. Still busy paying off the machine itself, even though it'll take me only a few months.

And just as I was typing, the UPS girl was ringing at the door, and delivering my replacement heatsink <3 ! Repaste, here I come!

 

But my guess is that with using CLU and optimizing Thermal Pad arrangement, Temps should be good either with T-shaped heatsink.

 

I just mounted the T sink and pasted with Gelid Extreme. Much, much, much better. Card is at a stable 67° under normal gaming load. That'll suffice for now. Let's see what I can eke out in the future.

 

Great to hear! Looking forward to seeing some temps and benches.

* I really fancy Gelid Extreme. It has never let me down.

 

Yeah, it's good stuff, though I'll have to buy some more and improve my spreading technique before I get into benchery .

 

I haven't had time to run any benchmarks, but I removed the master GPU and moved the slave to the master slot. Then did a clean driver install. So far everything is running perfectly fine. The crazy green pixels are gone and the code 43 device error is gone. It looks like you were right. The master GPU is dead/dying.

Please tell me if I am understanding it all correctly. If anything is wrong, please correct:

There's 3 types of heatsinks, regular single, T-shaped and vapor chamber (though I don't know the shape of the vapor chamber, single or T-shaped).
The DM3 comes standard with a vapor chamber, the DM2 does not. The DM3 is always SLI while the DM2 is a single 1080.
Question: is the VC an after market part or standard Clevo for DM3 that's optional by resellers for the DM2?

 

I understand your confusion. I've also heard terms like:

Grid
T behemoth
T Rex
Single heatsink
GPU/CPU combo heatsink
Unified heatsink

Keeping up with which is which is

 

To sum up, provided I'm not wrong:

The single-fan heatsink is meant for SKUs with a GTX 1070 configuration (single or SLI, albeit only a few manufacturers offer single-1070 units). The single 1080 version gets the T-shaped dual-fan heatsink. Both are sold under the model number P870DM2. The vapour chamber is meant for the 1080 SLI config (P870DM3), though some resellers also sell single-1080 SKUs with that specific cooling solution, which makes upgrading to SLI easier.

 

Ah, so by definition the VC would be a single fan cooling solution, otherwise you'd never get a second one in.
I'll accept that the VC cools better with 1 fan than the non-VC with 1 fan.
Question is if the VC with 1 fan cools that much better than the T-shaped regular sink with 2 fans... not taking upgrade path ease into consideration.

 

Actually the fans are a firm part of the chassis. You only take out the heatpipes. The VC is one large plate that covers both GPUs and has pipes linking to both fans.

 

The VC connects both GPUs to both fans.

 

I have a stupid question, but its better to be stupid than sorry.
How do the fans behave. I mean do all three run all the time (with different rpm depending on GPU/CPU load) or do one/two shut down when there is no load.

I would guess it would be former but just want to confirm.

 

Well at least you aren't completely dead. Cam you just send back the one card?

Sometimes they shut down completely when there's no load at all, but usually they run softly in the background, and move into gear independently from one another depending on load.

 

No, that is not correct. Please see my post just two pages back - **Official Clevo P870DM2/P870DM3 (Sager NP9873/NP9872) Owner's Lounge! - The Phoenix 2 is here!**

The GPU is not an after market part. It, and the heat sink appropriate to it, come from Clevo as a package.

.

 

I'm not sure yet. I'm waiting on the HID team to let me know what they will want me to do.

I feel like my gpu idle temp of 45c seems a bit high. Anyone with a single 1080, what are your idle temps? thanks!

lol thats normal bruh

 

im guessing its time for a direct comparison of those three heatsinks. anyone feeling up to that? @Mr. Fox @HTWingNut & the usual suspects

Perfectly normal. Lowest my GPU goes is around 37°C when under no load at all, but when e.g. cooling down after a gaming session, it usually stays in the 40s for a good while.

 

I'll gladly test anything that someone wants to send me. Which three heat sinks are you referring to?

 

Single fan, T shape and grid.

 

Thanks for that. I remember seeing 37c at idle a few weeks back on my gpu, before I repasted, that's why 45 c seemed a bit high.

Yes, the epic showdown.
One shall stand, one shall fall.

 

Now that I'm 100% sure about the t-heatsink, if you want to direct me to the set of tests and how to document everything how everyone wants it, I'd be glad to provide data one everything for this model tonight. On the top of my head, I'm getting 29C-35C Single 1080 temps on no load, and avg. of 62-72C on gaming loads with games like Overwatch, Rise of the Tomb Raider, etc (Overclock and Max fan settings). CPU has just barely hit over 70C during full Adobe renders for over 100 video files (1080p and 4K) at 4.3Ghz all cores. Avg. CPU sits around mid-high 30's while idle or basic use, moderate work brings the temps to the 40's, while hitting the 50's during med-high loads. I'll double check everything with documented info tonight if everyone wants it.

 

and the third? shall sit?

 

Don't forget to put max performance in Nvidia control panel.

 

This is why I was rooting for the single T shape heatsink. The temperatures seem to be so much better. And the processor doesn't have to bear the brunt of it.

 

The VC should have better cooling for single 1080 compared to T-shape.
As much as i dislike unified heatsinks, it has advantage in real life applications where you dont stress GPU/CPu at the same time.
Also I dont know what kind of VC solution clevo has implemented, i mean whether they are using VC just to pick-up the heat form CPU/GPU and transporting it through heat pipes or whether they have VC conneced directly to heat sink. If it former then its much better (in my opinion).
Regardless i fell that VC should do a better job then T-shape

 

For single cards , definitely. But it comes with the added effort of having to remove both heatsinks or st least the GPU side, if you want to do anything to the system .

 

The combined heatsink is using a single large vapor chamber, hence the all in one design.

 

Yup, you are right, its definitely is a negative point for the unified heat-sink.

 

You can get to all the other user serviceable parts without removing the heatsinks.

 

To me it seems like a hybrid of VC and conventional heat pipes, something like this.

Spoiler

But im not sure.

 

The vapor chamber goes up to the fins and does the thermal transfer. The heat pipes simply assist.

 

Damn! My girlfriend didn't hear the UPS driver, so I have to wait until 8pm tonight to pick up my beast. She knows I'm angry but I can't place all the blame on her. The UPS drivers that serve my area are like ninjas. They are quick and silent, able to throw up a "sorry we missed you" notice without anyone hearing anything. The driver did, however, leave six other packages on my porch without any care to hide them from view. Luckily, I live in a good neighborhood because those six packages contained some expensive computer components. Now to play the waiting game...

 

At least its not like when FedEx didn't find me at home at 10am, without even coming close to my building.

 

I get a lot of that at my office with FedEx and UPS. The receptionist doesn't leave until 5pm and even on her lunchbreak, there's someone at the main desk, and yet we get tons of ghosts "sorry" notifications that no one was there around 3 to 4:30pm. We still get these notifications even after our complains to sales reps for both FedEx and UPS to switch our mailing services from USPS.

 

For normal.packages I don't care, since there is a FedEx store close by and I can pick it up next day, but this was my P870DM. I literally raised hell after calling every possible FedEx customer support no. And making a copy of the reception security cam. The distribution centre manager from my area called me and had the driver drop it off within 2 hours. Freaking hate their laziness sometimes.

 

Ah yes...the infamous "Ring and Run"...it think that is in their training manual.

It is particularly bad for Saturday deliveries.

 

I picked it up! Getting ready to open up the package now.

 

Don't forget to get a baseline of temperature measurements before pulling it all apart and repasting.

It's a good idea to take some time to enjoy the new laptop and make sure everything is functional before pulling it apart. Maybe 24 or 48 hours to allow for infant mortality failures to show up.

You wouldn't want to go through all that work only to find you need to return it for another laptop because of an unrelated - or related - failure
