Introduction

Le faible facteur de forme rend le NUC trop enclin à la surchauffe en raison de l'accumulation de poussière dans les ailettes de sortie d'air du refroidisseur du CPU.

    • Commencez par utiliser un tournevis cruciforme n° 2 pour retirer les vis inférieures de la trappe inférieure du boîtier.

    • Ce vis restent captives, elles ne tomberont donc pas quand vous ouvrirez la trappe.

    What are the size of these case screws?

    • Soulevez la trappe et surveillez les câbles qui se connectent à la carte mère du NUC. Ces câbles sont les câbles d'alimentation et de données pour la baie de disque dur 2,5".

    • Débranchez soigneusement les câbles de la carte mère et mettez le support de côté.

    • Sur la dernière photo, l'emplacement pour un SSD lame est marqué d'une flèche rouge. C'est là que vous installerez le SSD lame et utiliserez une vis pour le maintenir en place.

    Hello, may I know what is the screw size? I already stripped mine so I'm trying to get a replacement screw when I have the stripped out. Mine was stripped and cannot get it out. Can you please help me? I've already used the rubber and glue method but no luck.

    • Retirez les câbles d'antenne WiFi et Bluetooth (soyez extrêmement prudent lorsque vous faites cela, sinon vous risquez d'arracher la borne de contact de la base du PCB).

    • Retirez le câble du micro stéréo du connecteur de la carte mère.

    • Faites attention au câble Wi-Fi caché sous un morceau de ruban adhésif noir.

    Remove WiFi an Bluetooth antenna Cable very carefully. Terminals can be ripped of easily.

    Christian Reinhold -

    very true, I’ll add it to the guide

    Vladimir Knobel -

    Added to the step in the guide, thanks for pointing that out!

    Vladimir Knobel -

    Note that the WiFi and Bluetooth antenna cables lift/pull off vertically (not slide off horizontally, as I presumed from the photo). They are circular connectors with a pin in the middle. Getting them off was okay (I actually used tweezers), but it was fiddly work trying to push them back on.

    Hallo, kann man den Lüfter auswechsel. Bei mir ist er nach ca. 15-20 min sehr laut.Ich glaube das das Lager defekt ist . Wenn ja, wo bekomme ich einen neuen her?.Für eine ausführliche Nachricht wäre ich sehr Dankbar.

    Mit freundlichen Grüßen

    • Utilisez un outil de levier pour soulever la carte mère hors du boîtier.

    • Entourée en rouge, la poussière évidente à première vue.

    Amazing! Could replace the fan. Have also removed the 4 screws of the heatsink , and renewed the thermal paste underneath it. That was necessary. It was dried out. THANKS!! It works like new: no overheating anymore. A lot faster.

    The key for getting the motherboard is to move apart very firmly the two opposite sides of the metal casing, so as to let the connectors move down.

    Jan Drouaud -

    Thank you Jan for that tip!

    I spent 20 minutes trying to jiggle it out before I read that!

    Yes, pull it apart somewhat and it comes out (relatively) easily.

    • Cette étape n'est probablement pas nécessaire, mais la voilà par souci de complétude.

    • Retirez les vis qui maintiennent le dissipateur thermique du processeur en suivant les numéros écrits dessus.

    • Attention à ne pas trop en mettre.

    Good morning, i'm tryinf to fix my nuc 8i5beb, I've found a burned component on the motherboard and I can't read the referance name. it's nead the connector right down the dissipator. can anyone help me? Thanks

Very helpful, thank you!

Ray Wang -

Great tutorial, thanks, now my fan is very clean and quiet. Thanks for spending time to create this guide!

Schüszterl Ferenc -

I did see this guide after finding out the same steps myself and having seen this guide before doing so would be very helpful.

Jack Graus -

Great tutorial. Clear pictures, solid instructions. Thanks a lot!

Koen Veys -

you are welcome

Vladimir Knobel -

Thank you. Awesome video! How often do NUC's get heating issues from average use? Is this also Intel's troubleshooting method, or would they ship a replacement NUC?

UTuberoni -

Thank you very much! This seems to be problem with NUCs because the first one I had was replaced under warranty after the fan quit but glad I was able to clean this to hopefully keep it running longer.

Patrick McNamara -

Glad it helped!

Vladimir Knobel -

Just what I needed and couldn’t find elsewhere! Thank you.

Nikolay Cholakov -

Great guide. Super useful, A+

Brad Thelad -

Hello,

Thank you very much for this tutorial.

What is the thickness of thermal pad?

L B -

Hi @L+B I don’t know which one you mean but I’m afraid I don’t possess that information.

Vladimir Knobel -

I own the same model as yours (8i7BEH).

I have bought thermal paste for CPU but not yet the thermal pads (for eDRAM and PCH) and was wondering what to buy before disassembling my unit :-)

L B -

Incredibly helpful, thank you! My NUC started blowing like a jet engine and thermal throttling and I realized it was hitting 100C temps. Followed this guide and found my heatsink / fan slots were completely blocked with fine dust - no hair or dust bunnies, but just plugged completely. Blew it out and am back down to 75C at max (transcoding) usage.

Answering two questions above:

- antenna connectors pull straight out from the motherboard. A pair of tweezers is a good tool for this.

- thermal pads are 1mm. came up as 0.7 on my calipers so assuming slightly compressed.

My personal mistake - if you find any of the screws connecting the outer case to the unit won’t screw down, check where you put the screws connecting the motherboard to the base. I had accidentally put a motherboard screw into a case screw hole and then couldn’t screw in that case screw until I moved the motherboard screw.

Taking photos as you go is a good idea!

solstyce9 -

Awesome guide. Helped me a lot!

trajche.manev -

Can you measure the distance betwen the holes that hold the cooling radiator ? I’m planning on upgrading it with a regular CPU cooler. Thanks !

Lucian Pop -

Great, thx! Works for Intel NUC8BEB / Wortmann Terra PC-Micro Sielent 6000 almost identical. After disassembling the unit, I applied a little WD40 to the noisy fan. Did the trick!

Tobias Baumhauer -

Thank you so much. I was able to strip the fan out and blew it out with my compressor. It still made a noise when I moved it with my finger (like it was almost off-center) sprayed a bit of WD-40 into it and more air. It is quiet (for now).

But, thank you very much again

Aubrey Kloppers -

Very helpful! I followed this for the NUC8i7BEK: the thin version of NUC8i7BEH without space for 2.5" drive. It was the same except for step 3, and I didn't need to remove any padding in step 11; could take motherboard out and back in whilst keeping them attached.

Step 17: I believe it's not good for the fan to make it spin fast like that. Better to hold it stationary while blowing with canned air.

I made the same mistake as another commenter with not putting in the motherboard screws back in the same spots, and then not being able to tighten the screws in the lid.

I skipped steps 18-20 as it was not needed for now.

Thanks again! NUC sounds much healthier now (quiet).

Bauke -

Excellent tutorial!

Have you ever thought of publishing this along your other services as a PDF poster, on paper? As a

modest ontology?

If interested, please mail,

Wolfgang

Wolfgang Bock -

Thanks for the guide. I was able to clear the dust blockage. Without the guide I would not have attempted it. I am still amazed at how poorly fan and cooling design is in 2022. It should be a simple thing to clear dust out of a system with filters properly placed.

Shaun Potts -

Great instructional!

It was indeed the cause of overheating.

Thank you man

Tzachi Halimi -

Has anyone tried something simple like a vacuum with moderate suction agonist th vent grill? J E Barnes, 11/29/22

John Barnes -

Thank you.
Very useful

Vadim Vadimych -

Perfect! Less noise, less throttling now. Performance improved by about 10% under load.

Yuri Kritsky -

Thank you for the help!

Rostislav Klein -

Thanks for the tutorial. Replacing the original thermal paste which was not applied properly at the factory (the paste did not completely cover the surface) was a game changer!

I used Thermal Grizzly Conductonaut (73 W/m K) as a replacement and on idle the computer now runs at 38-44° C instead of 65-75° C. Under load the CPU was throttling all the time due to its 100° C temperature and was simply unusable in some circumstances. Now it runs at 70° C on heavy load. It's a 30° degrees gain!

Philippe Docourt -

thanks for sharing! The heatsink was competely blocked by dust. Temperature decreased by 40°C.
