P650 Overheating

Hello,

So I've had my Eluktronics P650HS-G for a little over 9 months currently and it's starting to overheat pretty seriously. The specs are as follows,

Processor: Intel® Core i7-7700HQ Quad Core (2.8-3.8GHz TurboBoost, 6MB L3 Cache)
RAM: 16GB DDR4 2400MHz RAM
Display: 15.6" Full HD LG® IPS 60Hz EDP Matte (1920 x 1080)
Graphics: 8GB GDDR5 VRAM NVIDIA® GeForce GTX 1070 + G-Sync
Primary Drive: 256GB Performance SATA III SSD
Secondary: 1TB 7200RPM SATA III Hard Drive

Lately, I've noticed the CPU temps hitting 95c and above on prolonged heavy load gaming sessions playing PUBG. That is by far the worst example, as playing Overwatch (at 154fps, 1080p) brings it to around 88c. GPU temps aren't nearly as bad, topping out around 85c but usually right around 80c.

So has anyone else dealt with this? I'm planning on opening it up and clearing out all the dust. I tried contacting Eluktronics support and they are saying reapplying thermal paste voids the warranty (which was my first instinct.) So any other suggestions before I go ahead and reapply paste?

So far I've tried limiting CPU usage to 80% in power settings, playing on max fan settings in the Control Panel and undervolting the CPU a little in Intel XTU.

Thanks

 

Use compressed air in the vents while stopping the fans from spinning use a screwdriver or the like.

 

Make sure the machine is off first though!

Have you considered frame-capping? Since you've only got a 60hz panel there's not all that much use in running 150+fps unless you really like screen tearing. It doesn't address the issue directly, but it should reduce your temps by reducing load.

Lastly, I'd consider re-pasting. The 7700hq is notorious for hitting 90C in any machine.

 

I took it apart and blew compressed air anywhere there was any dust (but there was barely any.) Haven't had a chance to test yet tho.

Edit: It didn't have any effect. CPU still hitting 95c

 

I do frame cap PUBG at 90 since that's all I can reliably hit via MSI Afterburner. And I'm running an external 144hz monitor.

 

What are your room temps like? What were the original temps?

 

I would say you're looking close to having a repaste. Mine is like now. It came with ICDiamond paste and tempts started to creep up at about 9 months mark. Just over a year now, and if i were to do prolonged games, would hit high temps like yours.

 

I'm not sure they are legally allowed to just claim your warranty is void either...

 

get ICDiamond and repaste, then do some undervolting etc. that way u'll be fine.

 

Ya I'm probably just going to repaste and see what happens. I would just send it in for repair under warranty to have them take a look, but I'm a freelance web dev and can't be without my workstation for that long.

I picked up some Thermal Grizzly, always heard good things about it. But I've heard ICDiamond referenced a lot around clevo chassis. Does it outperform Thermal Grizzly? Or is the difference negligible?

 

Depends on your heatsink, usually ICDiamond outperforms other thermal compound due to the pathethic heatsink fit from clevo systems.

 

ICD7 or Gelid Extreme would be a good match

 

Gotcha, thanks for the replies everyone. But, do you think repasting will make that much of a difference? Is there potential to drop the temps by 10c? Because dropping the temps by 2-3c would be good, but it would mean there are still Thermal problems. I believe Eluktronics used MX-4 on the basic builds that don't specify ICDiamond.

 

if your current thermal paste dried out etc. then you'll likely lose 10-20c.

 

Gelid GC Extreme is highly recommended for laptops. One of the best heat reducing Tim's. Within the top 4 Non-Conductive pastes

 

I ordered ICDiamond. Will update after a repaste.

 

Thermal grizzly is also good if available. Good luck with the repaste.

 

So I was planning on repasting myself (with the help of a video from Bob of all trades on YouTube where he repastes my same laptop but with a GTX 1060.) But, it turns out the CPU and GPU heatsinks are connected and that scared me off.

I don't have much experience with laptops (even though Ive worked a lot with desktops) so I'm talking to Eluktronics about turn around time on a repaste.

 

Do you see the screws are numbered from 1 to 14? Those are the ones you need to remove to take the heatsink off.

 

It's pretty straight forward in that you just undo all the screws in order and the whole thing comes off as one unit. The obvious side-effect being that you have to re-paste both CPU and GPU whenever you do it. Also take care to keep an eye on the thermal pads as some might stick to the heatsink and some to the board when you lift it all off.

It also gives you a good opportunity to clean out the inside of the heatsinks. That is the tiny gap between the fan unit's and heatsinks. I've found in several P650 models I've cleaned that if they've been in dusty environments that it'll block up on the inside.

 

So it's just those 14 screws and the whole heatsink pops off? I saw the numbers and considered that may be what it's for but wasn't sure. If that's the case I might go for it.

 

Yes, there may be some resistance from the thermal paste and pads but gently wiggle it and pull up from a corner.
