15r2 heat sink/skateboard?

Hi,

Anyone seen anything like this? I just removed the heat sink to repaste due to erratic fan noise and found this, the cpu and gpu looked just like all the other pics, btw. The scratches are easily felt.




I was early in line for a fully loaded 15r2, all was good and then I came home, turned my laptop on and my 15r2 smoked briefly and then shut off. I sent the laptop back to Dell, they fixed it in a respectable time, sent it back, and I have lived with it since, no issues gaming etc. Only issue I have had is erratic fan noise which has become annoying, so I followed instructions here and opened it up for a repaste.

My warranty is almost up, I will be calling them when they open

Thanks for looking

 

this is not going to reduce the heat transfer performance ... the scratches are superficial .. nothing to worry about

 

Thank you for the info!

 

Wait no

When you can actually FEEL the scratch, it'll impact temp since there's an extra gap that needs to be filled by the paste.

Request a new heatsink unit that you can install by yourself, because it seems like that the tech person remove old thermal paste by screwdriver! @Papusan

 

THANK YOU! That is exactly what they did, I was trying to figure out what happened, makes sense now, will do!

 

you are a heat transfer expert hahaha like your K5 pro recommendation XD
in fact I scratched my heatsink with sand paper and is working better than desired

 

@struggles the clevo guys think that they know too much about heat transfer ... but the real thing is that the worst stage is when the gap between the heatsink and the cpu or gpu is not uniform ( is not making good pressure) or the gap is too big

 

I will call regardless to see if they will send out another one, paying a premium for a product and seeing this is frustrating. Just happy to understand now where these scratches came from, must have been a Monday repair.

 

that is different .. I understand you. but is a lie say that is going to reduce heat transfer these little scratches ...

 

Got it, thank you for the input

 

if i was you, i wouldn't bother too much with that, because is not good fully disassembling and assembling your laptop too much times for cosmetic reasons or probably you could damage some flex or whatever

if you have good temps after repaste, you should be happy

 

Ask Dell to send a new heatsink and do the work yourself!! This is completely normal work from Dell tech support(even worse with home support - see my post below). Even their new AW models come with useless max temp. + 95C under load with a low powered 6700Hq@ 3.1 GHz.

Spoiler: WHAT???

Of course those scratches on his heatsink destroy the cooling. Everything else is nonsense. The one who specify otherwise... I have no words bro!!!

I think bro @Mobius 1 know more about thermal and heat transfer than you. Your post telling that the scratches on his heatsink doesn't matter... Showing your huge knowlage!!
Sanding and prep the heatsink for better thermal, is different than sand down scrapes. So you make scratches first and then use sand paper? First time I have heard this, LOL

And most part of Clevo boys manage to fix temp problem. Why do you think we manage to run +4.8 GHz cpu clock speed in laptops?

Defend the brand they prefer whatever they do with your computer. Oh' well. I haven't words
Look at the pictures below. Home tech take off the old thermal paste with a screwdriver and then apply new thermal paste with a shovel... I did not reach to speak, before he devastated the entire heatsink. Then I showed these tests to Dell in email. Dell sent me a new heatsink which I installed myself. The max temperature fell down with a bang. And the tech... He lost his job Yeah, Dell hire useless tech for home support. You can find the whole story in the forum(if you can or have learned to use search) You can also search with Google

 

@Papusan
i have fully scratched my heatsink and i have really good temperatures, without cheating ... obviously you dont know what i am talking about, and i am not going to try to teach you things that you are not going to understand.

because you think you are right, dont ensure you are right. you have worst scratches on the heatsink than him.

you only know copper is copper and thermal paste is thermal paste ... i am not going to be your professor, study if you want to know more

 

Do you still not understood it? Sanding and prep the heatsink for better thermal, is a lot different than sand down scrapes(from useless ****y tech job) with the following problem that the pressure from heatsink drops. Regarding different paste... I don't use standard paste. I prefer Liquid metal. Why do you think we can run 24/7 with 4.8 GHz on processors in laptops?
So it's okay to receive back the heatsink in this state?

Spoiler: OH'WELL

 

That's a terrible job. Even as a n00b, I realized that scraping paste off with metal, stabbing-things was a bad idea. Hopefully Dell replaces it, given that it's been done through pure negligence.

To be fair, I bought a used system and it had similar marks to the heatsink and I could feel the scratches with a thumbnail. Cooling performance with ICD was fine. The fan broke so I bought a new heatsink unit to replace it and it didn't have any damage. With ICD used again, the performance was the same. Replaced it with CLU and the cooling improved - but that generally happens when you switch to liquid metal. System CPU had OC but it wasn't a huge amount.

Those marks would make CLU less viable IMHO but a thicker paste like ICD should be OK. A new heatsink wouldn't hurt anyway but I'm not sure it's the end of the world if Dell refuses.

 

I gotta be honest here, 1 deeper scratch doesnt affect thermals that much. It really doesnt. But I still wouldnt accept it. I like my stuff in pristine condition.

 

I agree with you that *small* scratches does not make the biggest difference in temp. But remember people strive to get the best thermals, not the opposite. Scratches don't mean better temp. But give this idiotic advice to those affected... <nothing to worry about>. Is objectionable / not a acceptable advice. If this Dell tech can continue with such shhitty job.. Isn't good. He should do something else and not touch / repair someone's computers any more. Aka If all follow his ↑↑↑ advice... No one cared and does not alerts Dell... Can this tech proceed with destroying others costly products.

 

One thing is for certain: your screwed up heat sink won't work better with those scratches. And, that level of incompetence cannot be ignored or dismissed. They need to replace what they screwed up. The person that did it needs to be fired. They have no business touching another person's computer.

 

Thank you all for the help and insight, Dell said it was "cosmetic," but they were kind enough to send a refurbished heatsink.
