PS4 Pro Liquid Metal vs Thermal Paste

Testing Thermal Grease and Liquid Metal on the PS4 Pro CUH-7015, CUH-7016 - the hottest and noisiest of all PlayStation 4 Pro models.

*DESCRIPTION*
Welcome to HowFixit, in this video, I will test the effectiveness of thermal paste and liquid metal on PS4 Pro. I chose the first revision of PS4 Pro CUH-7016b (the same CUH-7015b, CUH-7115b) it is the hottest and noisiest of all PlayStation 4 Pro models.
Before testing the thermal paste, the game console was completely dust-cleaned. In this video, I do not show the detailed process of disassembling and cleaning the PS4 Pro, there is a separate video on my channel.
For the test, I chose the most popular Arctic MX-4 thermal paste and Thermal Grizzly Conductonaut liquid metal.
To measure the heating temperature of the PS4 Pro, I will use two sensors: the white sensor I'll connect directly to the heatsink, and the black sensor will measure the temperature of the air blown out of the game console's cooling system.

Explanation of the ending for those who didn't understand the result of the test, why liquid metal is better for PS4 Pro - the sensor was attached to the heatsink and the temperature is higher for liquid metal because it transfers heat from the APU to the heatsink better. Please do not confuse the processor heat level with the heat sink heat level. The purpose of a heat conductor is to better transfer heat from the CPU to the heatsink, in which case liquid metal did a better job than thermal paste.

Liquid metal is always better than paste at heat transfer, but you have to be careful on bare copper heatsinks because of dry out of the LM. The copper will absorb the LM and you'll have to reapply it a couple times. It's best to use it on nickel plated surfaces to avoid this

Applied liquid metal to my ps4 pro 6-7 months ago. Result was great but yesterday fun went to max speed. I disassembled ps4 pro and found liquid metal became dry and penetrated into a copper cooling plate. So I spent 1hr removing "liquid" metal. Damaged mirror surface of cooling plate. Finally applied new thermal paste with highest efficiency. All is great now. Never come back to liquid metal for ps4 again

I bought a ps4 pro first Revision with liquid metal applied nearly 2 years ago. I opened it up because of the quite high noise level. I noticed although the ps4 pro had a copper heatsink it still got damaged over time and lost contact to the board. After reapplying mx4 the fan noise dropped significantly.
All of the reviewer said that copper heat sinks are resistent to liquid metal. However, I cant confirm that.

[bardockofalecido]

You missed the part where the liquid metal will fuse with the hs.. the PS4 Pro was not designed to have liquid metal as a cooling option

[grimfandangox]

Liquid metal should also be applied to the heat sink

[DazDaz]

I applied MX-4 to my PS4 Pro quite recently and it's now so cool and quiet that I don't remotely feel any need to go with liquid metal.

[leoyser]

You shouldn't put LM without foam around to keep it from dropping into the motherboard

[joelmichaelviado]

I used a thermal grizzly carbonaut graphite pad on my ps4 pro based on tbe recommendation of a channel on yt. Never had problems with noisy fans ever again and the exhaust vented the heat better than ever. I used noctua thermal paste before but it didn't last a day before the noise came back.

[bruh-txtb]

It's great and all but I'd rather take the one with thermal paste. Because regardless of less heat by a few degrees it'll still perform the same anyways because of how it's designed to do.

[alexandr_nem]

for the accuracy of the experiment, it is necessary to fix the fan speed at the same level

[viniciusferri]

IMPORTANT: The thermal paste used in this vídeo is the vídeo MX-4 that have cure time 200 hours, after this time the temperature going down 2°C até 5°C, and after applied the paste MX-4 can during for 8 years validity

[JoaoPedro-kict]

I am no expert when it comes to cooling, airflow, temperature and whatnots, but the difference seems to be rather too minimal to be worth the extra hassle in my opinion.

[ValkyrianWyverian]

Thank you for the test. I've resorted to using a graphite thermal pad for my PS4. It's a one and done application, and I don't have to worry about constantly reapplying paste.

I don't know what the long term effects are like, but I haven't run into any issues in the past year.

[videocardzrule]

Liquid Metal works great! But after 1 year, my sons Xbox was having issues. So I went back to thermal paste, because I didn’t want to take it apart every year lol.

[KainArkanos]

I think the results could've been better honestly. In delidding CPUs for PC, you're told to apply LM both to the CPU die itself and to the heatspreader to help avoid pockets of non-contact since LM isn't viscous enough to really spread and reach out well enough for contact.

[MeguraX]

Efectivamente hay mejor transferencia de temperatura al disipador, lo que se mide es la temperatura de este último, si aumenta con metal liquido indica que hay mejor transferencia térmica, por lo tanto menor ruido en el ventilador y condiciones más favorables para el APU.

[kompst_tu]

So it appears the liquid metal made things worse. That or there was no difference in temperatures other than the fan being "quieter" which just means they spun slower, which is definitely going to mean higher temps. Waging on the temperature difference being nothing more than the cooling system not keeping up fully yet and that there is no difference in temps between these two pastes.

I don't understand liquid metal with 64 sells thermal paste was 60 so it's cooler air temperature liquid metal 56 Celsius thermal paste is 52 the only thing it did better was fan noise

[shanthoshravi]

I tested it with a jailbroken base ps4, where you can monitor CPU temperature, and the die went from 85 degrees on stock with high fans, to 76 degrees with minimal fan.
