I'm debating whether or not to replace the thermal paste in my Lenovo y510p. I've started overclocking a bit, and I have an external fan, but I would like to not have to run the fan as fast because it is a little loud. I have been reading a bit about different thermal pastes, and I'm wondering if there is even a big difference between stock thermal paste, and something like the liquid metal from thermal grizzly. It sounds like it'd work better, but I don't want to fall for a good marketing scheme. If anyone has experience with this and has or hasn't seen big differences, your input would be greatly appreciated.
Thanks in advance!
I recently upgraded my M15x with a i7 920XM and a GTX 780M.
Flashed the modified vbios, got a 330W brick, pulled the pin, installed newest drivers and did some gaming.
Everything worked pretty well, only sometimes the 780M reached 93C and clocked down, but still ran stable, never crashed.
Therefore I decided to get a finer TIM and repaste. Bought the Noctua NT-H1, carefully repasted and voila, temps dropped around 15C.
But here comes the catch: when trying Furmark or some very intensive game, the GPU reaches 88C and screen immediately turns a random color. No downclocking, no limiting, just a sudden crash. Only thing I can do is a hard reset. This doesnt happen on any other occasion, can game on 80C for an hour.
Do you guys have any sort of idea why the laptop crashes at 88C, while before it worked at 90+ without a problem?
Things I tried:
Used DDU and reinstalled the drivers, also tried older version.
Cleaned everything, no dust left anywhere.
Carefully checked the GPU for any visible damage or old TIM residue.
Tried undervolting and underclocking, only took longer to get to 88C and still crashed.
For the sake of it I actually strapped a Corsair H45 AIO to the GPU heatsink. Now i get to max 55C with furmark, but the laptop still cashes after around 2 minutes.
I would be happy for any suggestion, thanks!
Hello All. I have a question:
I need to repaste my laptop. To clean the old thermal paste, i went to the pharmacy and bought an acohol solution with 78% alcoohol (highest content they had).
However, the same solution is also 2% salicilic acid. There are no other components in the solution (except 20% water). Can i usr it to clean the CPU anyway?
Thermal Paste Complete: Mandatory. Not an Option.
* Don't mind the MX4 LOL that was just left over from something... How about that toothpaste that is rated at 401w/mk...which happens to be the thermal conductivity of copper.
I will be repasting the P775DM3 very soon and will be posting up the results w/ a lot of pictures for your entertainment. My liquid metal paste of choice will be Grizzly Conductonaut, however, I'll be experimenting with other pastes as well to satisfy any curiosity as to if one can get by with just traditional paste. (Highly doubtful, but I am curious about GC.)
Traditional paste wise, I have a feeling that GELid will hold up pretty well.
While I'm at it, I'll also be replacing the thermal pads. Depending on how warped the heat sink is, I have pressure paper handy to be able to test the contacts of the die and IHS against the Heat Sink. If needed, I have copper shims standing by of varies sizes from 0.1mm to 0.3mm+ ...
Below are the conductivity numbers for the top Liquid Metals and Traditional Paste:
(As we know the numbers don't mean everything, however, from all my tests done so far, Grizzly Conductonaut has always topped CLLU by an average of ~3C. Results may vary and it can be the case where it's the other way around. However, the thing here is that with these beasts, every drop in C's count. It could make all the difference.)
Thermal Grizzly Conductonaut - 73 W/mk
Coollaboratory Liquid Ultra - 38.4 W/mk
Coollaboratory Liquid Pro - 32.6 W/mk
Gelid GC Extreme: 8.5 W/mk
Grizzly Kyronaut: 12.5 W/mk
ICD: 4.5 W/mk

Straight out of the Box:
The temps when running OCCT on the CPU reached 99C on all four cores. Even on F1, the CPU temps all maxed out. Yikes right? As for the GPU, when running Unigine Heaven and Fire Strike the Temps were also in the high 80's and 90's. Repasting is a must IMO. 90C's is not okay and there's no justifying that. I know it's such a shame on Clevo's part for poor QC and lack of engineering (as demonstrated by the crap ADDA fans that are used), but it is what it is. If you want something to just work out of the box without any modding, then a DTR is not for you. Simple as that. Yes, it should work within normal operating temps right out of the box, of course, we would all agree. A DTR is for enthusiasts and those who have the willingness to get under the hood. Some of us thrive on this fact, while others don't, but at the same time this doesn't give Clevo an excuse to go cheap on us.
Project Delid + Liquid Metal Magic: (9/22/16)
The Repaste and Delid are now complete. I've been gathering temp data non stop, along with fine tuning the machine to find where it is the happiest. The temps have been amazing and I'll be posting up a full review shortly. - Stay tuned...
Fine Tuning: (9/25/16)
It's been a blast fine tuning the beast and I think I've got it to near optimal range. The CPU is a winner in the silicon lottery, thank goodness. I'm holding 4.6GHz @ -200mv Core / -200mv Cache and it's very stable with gaming, running benches, video encoding etc...As for the GPU, it's a working progress. After about 100+ runs...yes really of fine tuning and recording data on a spreadsheet, I think I've found the GPU's sweet spot. It's not a massive overclocker chip, but it's good enough to get a great boost out of it. Then again, my expectations are very high so anything sub par is not good enough. I'll be running more benches tonight and hopefully the tuning will pay off to take the #1 spot int he P775DM3 Class for Fire Strike, Unigine Heaven, Cinebench R15, Time Spy, wPrime (already recorded and sitting at #1 in this class) etc... I'll keep you all posted!
Please post your results using the format below in order to keep things uniform and organized:
