Clevo P650HP6-G (ish) overheating problem

Hello, I've a Monster Tulpar T7 v10.1 which is very similar to Clevo P650HP6-G. The only differences I can spot from the pictures and the spec sheet is that mine has fingerprint sensor and 1080p 75 Hz IPS G-sync capable screen instead of 120 Hz TN panel. Anyways my laptop overheats a lot. GPU gets to 95°c and my cpu gets to 100°c. I've reapplied the thermal paste 4 times but I think the problem is with the fans. Its bottom cover gets ridiculously hot and I can barely feel any air coming out of exhaust ports when the fans are blowing at full speed which shouldn't happen? I think the fans are blowing hot air into case not out of the case. Can something like that happen, I've checked the fan plugs they can only be inserted in one orientation. Also there is no dust build up. I'm lost here.

Thanks in advance for any help.

 

Can you use the (fn + 1) maximum fan combo and test again with elevated backside of the laptop.

 

Fn+f1 controls touchpad in my model. I'm already using max fan speed possible, set it to max in clevo control center. Still getting ridiculously high temps. You said elevated backside, how can I elevate the back side?

 

If you're at 95/100C, I don't think elevation will solve the problem... but, it's a pretty cheap experiment.

Simply get one or two small items that are ~2-3 cm high and put them under the rear of the laptop so it sits at an angle. Anything will work, e.g. set the center-rear section of the laptop on the corner of a thick book. Just make sure whatever you use doesn't block the air intakes at the bottom.

You have two GPU one CPU fan. Are all three fans behaving similarly?

 

Ok I'll try. Yeah all of them behave similarly. I can feel a little air out of exhaust ports when they're at full speed but that's it.

 

Fn+ 1, not Fn+F1

 

Exactly . I never said fn + f1.

 

Yeah I've misread sorry. But it's still the same. I even underclocked my cpu and gpu and also disabled turbo boost. Still getting 90-95°C cpu and 90-95°C gpu temps. Something is seriously wrong but I can't figure out what.

 

What thermal paste did you use? On a CLEVO you need something very thick like ICDiamond otherwise you can never keep temps in check.

This is the thermal paste that I've used. It's not the best but it was the best which was available in store. I've also used Noctua NT-H1 in the past. Same thing also happened with that.

 

I tried this paste before. This is by far the worst thermal paste I used in my life.

There are German sellers on ebay that sell ICD and ship to Turkey. Give one of them a shot.

 

That paste is electrically conductive right? Anyways I'll look at eBay.

 

No sir ICDiamond is non-conductive. I wouldn't recommend you go down the liquid metal/conductive thermal paste if you have such heatsink.

 

Sorry to hear that you're having thermal issues.

Has the laptop always done this, or did it start to overheat recently? If it started recently, was there an event that also happened around the same time?

Based on the pictures you included, hot air should be coming out of both the rear and the side of the laptop. If air is somehow being sucked through the rear and side, and blown out of the bottom, then yes, you have some sort of fan polarity issue. With the fans at high speed, can you tell us where air is exiting the laptop?

At those temperatures, the air exiting the laptop should be hotter than hell, and you should be able to feel more than a 'little' bit of air flowing.

What is the ambient temperature of the room the laptop is in?

With the information you've provided, I am guessing that the fans are not spinning up to full speed. At full speed the fans should be annoyingly loud, and plenty of hot air should be exiting the laptop.

If there is plenty of air exiting the laptop, but it isn't relatively hot, then heat isn't transferring to the heat sinks properly. There are only two places where heat is exchanged (other than the constant heat exchange inside of the heat pipes). One is between the CPU/GPU dies, and the other is between the heat sink fins and the air that's being pushed through by the fans.

The answers to these questions should help us to help you.

 

It's been like this since I've sent the device for repair. It had a fault keyboard which they replaced and also did thermal paste renewal. Since then it overheats. I've tried undervolting my cpu, gpu and even went as far as applying liquid metal. Still overheated like a manica. As for airflow, I mean I feel a bit air that is warm but not like I can't put my fingers near it hot. But bottom cover gets so hot that I can't even pick it up and hold the device in my hands. I can also confirm that fans are annoyingly loud so they do their job. I've ran the machine without its bottom cover on and the fans were blowing towards where the bottom cover would be.

 

Repaste with good thermal paste, sounds like the repair center used cheapo toothpaste.

 

If this started after they messed with it, and nothing changed even after you re-pasted it yourself, I'm wondering if they didn't screw something else up in the process.

If the fans are running, the air is not hot (it would be at those temperatures), and the bottom is getting extremely hot, then @senso is probably right about getting some better paste and doing the job again. There's a heat transfer issue between the components and the heat sink from the sounds of it. If a new paste job with proper paste doesn't change anything, then there's a contact problem with the die(s) and heat sink. You have dual GPUs, and both of them, as well as the CPU are overheating? Another issue could be that they used thermal pads that were too thick, and the CPU and GPU dies are not contacting the heat sink properly. This is all speculation since I can't work on the machine directly.

Also, if the bottom of the laptop is getting as hot as you say it is, I wouldn't use it under a load until you figure out what the problem with the thermals is.

Every laptop I have owned pulled air from the bottom, forced it through the heat sinks, and exhausted it out the rear or sides. That doesn't mean yours is supposed to work that way though. One question: are there small arrows on the top or bottom of your fans that indicate which direction the air is supposed to flow? Most fans will have these arrows, and all of the fans I've seen had the arrow pointing toward the open end of the fan case.

Something is amok here, and I am interested to see what the problem ends up being.

 

I can't find ICDiamond anywhere even ebay. Would Arctic MX-2 work ok? I can get that hassle free.

 

thermal grizzly kryonaut

 

Ok, I can also get that one easily. Will report back once I get it and apply it.

 

That one is not thick in anyway. It will not work.

Here is a link to an IC-Diamond posting that ships to Turkey.

 

Kryonaut is pretty thick!

Thicker than Artic-MX4..

I have been using Artic MX-4 for 4 years already, got Kryonaut when it got out, and Kryonaut is thicker than the MX-4, both work wonderfully in laptops, Kryonaut wins over, buts its like a huge difference, good heatsink contact will make more impact than crazy thermal pastes.

Just last weekend I lapped my GT72 CPU heatsink, re-applyed Kryonaut and it stays at 62-64ºC playing BF1 on High settings without even using the fan boost button(but I'm running a custom fan curve on EC via Svet EC editor, at 62-64ºC the fans are around 50% speed, and they make almost no noise compared to the full speed fan boost that sounds like a jet engine).

 

MSI heatsinks are far superior to some of the old Sager laptops like mine. Maybe it is different for newer machines.

 

Well heatsink design has been improving a lot in the last few years.

 

It's actually P670, not P650. P650, a 15-incher has far better ventilation under the case. Mine also gets around 96 and 71*C on CPU and GPU respectively while using Prime95 and FurMark altogether. However, I have had my motherboard replaced and I think my temps actually worsen after the replacement too. What method do you use when applying thermal compound?

 

X for square dies, thin line for rectangular dies for thermal paste.
