CLEVO i7-8700k --- IS IT TOO HOT??? $2400

Hi guys.
New user here.
I just bought my first custom built Clevo laptop for my 3D modeling and 3D renderings on the go.
Specs include the legendary 8700k CPU.




I ran my 3D Software and recorded my temps.
Are they high? Because the fans were pushing out super hot air.
I did the test again but this time I removed the bottom cover (to allow more cool air) and elevated the back end of the laptop by 2" off the table so it can draw more cool air.

Screenshots included.
Give me some advice here guys plz.

BTW thermal NT-H1 thermal paste was used between CPU and Heat sinks.

Start-up temps (no load, no software running)



Began 3D Rendering w/ Closed bottom lid - fan runs at full speed (loud)


Began 3D Rendering w/ bottom lid removed + suspended laptop 2" from the tabletop

 

That is too hot, you should undervolt the CPU slightly to lower the temps. If you want a final solution though, you will need to delid it and put liquid metal between the die and IHS - should lower the temps by 10-20 degrees.

 

Yeah that seems way too hot although those are pretty high clockspeeds. I think your question may be better in the clevo forum section to see what users there are doing. I would second undervolting it and repasting at the bare minimum. My desktop processors have all had 15-30C drops with delidding like @Arrrrbol mentioned. But depending on your level of experience that may be a huge undertaking. There are places that you can send your cpu in to be delidded but I've never used them so I can't comment on that.

 

Undervolting and/or de-lidding is an absolute must. Repasting by itself probably won't help more than a few C at best. Many who post in the P775 forum seem to complain about the heat because the chassis is smaller than its big brother, the P870.

 

This. Delid is needed to really get full use out of it, and even then overclocking is possible but not to the extent of the thicker and larger chassis. I have the littler brother P751TM and it's an even smaller chassis. With delid and 60mv undervolt I peaked at 85 after 7 mins of handbrake and CPU at 120w (still too hot but I can deal with it).

 

Thank you for all of the replies guys.
Deliding is out of the questions since laptop still has a warranty.
I spoke to the seller (Pro-Star) and they have been terrific people to deal with (thanks Jeff), and they will take the laptop back in for a full refund, so that puts me back on the market for a replacement that runs much cooler but still offers great CPU performance.

I was looking at some laptops with 8950HQ - anyone knows if that CPU suffers from same heat issues as the 8700K?
(knowing that 8700k is a destop CPU and the 8950HQ is a laptop CPU) - so I'm hoping that the i9 has been made to run cooler since it wad destined to be in small enclosures?

Thanks guys.

PS- I couldn't find the "Clevo" section on this forum.

 

Where did you get this laptop?

They are awesome guys.

 

That is definitely too hot , this is what my Dm3 can do using the TM1 CPU heatsink (Mind you the ambient temperature was at 30C)-







With he ambient temperature being that high, this is pretty darn good. Once i turn on the AC and drop the ambient to 22C-24C, the system temps drop by another 5-7C while running sims in Houdini or rendering in Redshift/Vray.

You definitely need to undervolt though, 1.3V for those clocks is rather way too high and will generate too much heat.

That's the Sager/Clevo owners forum. If you are looking to buy again, I suggest HIDEvolution.com since they offer de-lidding and other mods on various systems and cover those modded parts under warranty. Their sales and support is stellar (no, they don't pay me)

edit: kudos to pro-star to do what they can to ensure you are a satisfied customer.

 

Call my cynical, but I highly doubt the i9 will run any cooler. Every "gaming" laptop I have seen in recent years (with very few exceptions) thermal throttles out of the box. Temperatures might be acceptable after a repaste - but you will never get the performance of an 8700K. Its a Clevo issue too, their laptops also throttle out of the box as you have discovered, but at least they have the excuse that they are using desktop CPUs rather than BGA mobile ones which don't even have an IHS.

If you need a 6 core CPU, buy a Clevo from a reseller like HIDEvolution that will delid and undervolt the CPU for you. If not, some of MSI's stuff might potentially be alright, though I haven't seen their Coffee Lake stuff yet so don't quote me on it.

 

The only reason why the i9 in the MSI's MIGHT run cooler would be because of lower clocks and undervolts. And of course, the paste jobs done by HIDE helps as lot as well.

 

This is what I was going to say. Yes it might actually run cooler, but it's a 45w cpu, and will not hold higher clocks well. So at a significant reduction in performance it will work. You may even be better off going with a better quality overclockable 7820HK/6820HK that will hold higher clocks and come out ahead for your work loads.

For serious work which it seems like you are doing, I would stick with the desktop CPU. Check out all the Clevo models available and see if any will work better for you, and especially one with delid and Prema BIOS.

 

What voltage should I undervolt it to?
I just installed the Intel Extreme Tuning.

 

In F2 BIOS boot menu's "OverClocking Performance" > "Processor" menu section set:

- "Voltage Mode" to "override''
- "Voltage Override" to "1100"

 

Just went to "Cores" tab in Intel's Extreme Tuning and offset (undervolt) the CPU -0.150V
Here are the new results rendering exact same image:

 

Spoiler

This is Phoenix GT 75 with the I9 CPU from HIDEvolution. He has temps between ~65 (gaming) - 75c (100% core usage stresstest)

@ shapenautics
Get the GT 75
http://www.hidevolution.com/msi-gt75-titan-056.html

The moment you buy a system that cant keep itself cool out of the box for a lot of money you should give it back and get something that actually works.I'm pretty sure once you recieve the GT 75 you will be a lot more happy with it, since its superior in almost every aspect.

 

Hi @Prema, which is the difference between using fixed override and adaptive + offset with negative mark to undervolting clevo's cpu? Regards

 

Those short run temps, for anything meaningful the load needs to be running for at least 15 mins.

Just like how this is pointless -

I personally never use XTU, would suggest doing what Prema suggested earlier. Also try dropping it further down to -0.175 and see if it remains stable.

Another thing i wanted to ask was, is the back of the laptop raised up about 0.5-1 inch up ? These laptops need room to breathe and enough space to pull in fresh air.

 

Sorry, forgot to mention that...the last rendering test run was done with my back cover completely removed and laptop being elevated about 1.5-2" off the table to allow adequate cool airflow.
Still hitting 100°C!!

I lost all faith in 8700k being used in laptop without water cooling.
Even talking to a rep from HIDevolution, with 8700k delided, binned, undervolted and max temps still will be 89°C, and I wouldn't be surprised to see it reach even 90-91°C - but costs a small fortune to even get all that done. :/

So I'm REALLY looking for "weaker" solution that will not self-destruct or melt from rendering my 3D images. LOL

 

Ran Cinabench, no bottom cover, laptop suspended from desk 2".

 

You really need to delid. You shouldn't be hitting anywhere near thermal throttling at stock.

Also try max fans (Fn+1).

What are your ambient temps, and which Clevo is this?

 

There are laptop solutions with an 8700K that don't require water cooling (such as my HID P870TM1) but they do absolutely require certain modifications to run cool under load. For instance, I have a dual vapor chamber heat sink with only a single 1080 and I can overclock the snot out of it and it never goes over 85C. The CPU is de-lidded, pasted with liquid metal and while undervolted 150mv (adaptive), it still runs 4.8 on all cores and stays well under 100C.

The 775 is simply too small a package to run stock under load with decent temps unless you get lucky with cool running components or mod some parts.

Bottom line, if you are rendering be prepared to spend big bucks to keep it cool, or choose a processor package that doesn't generate excessive heat at max load. How does the saying go, "Fast/Cool/Cheap", choose 2.

 

LOL true that.

 

What's your voltage for 4.8?

Can I pick Fast/Cheap?

 

HIDEvolution rep is correct, but depending on the system they do make sure that the CPU is properly delidded and makes proper contact with the heatsinks. Which definitely helps a LOT.

For stock systems, with stock pads and a non delidded CPU it will almost be impossible to tame those temps.

 

Rarely goes above 1.29v under load.

 

Get a Clevo P870 with single GPU and a delidded 8700K and you will be fine:

You can probably get close to all three...with a LOT of work or a huge system. Have to balance out whats worth it to you.

 

The top parts even modding the old equipment can still be expensive of course.
