Question Best Thermal Paste for USED Noctua NH-D15s?

[Nervly]

Hello, I just purchased an used Noctua NH-D15s so it doesn't bring Noctua's stock thermal paste, which means I'll have to buy the paste separately.

What is the best one I can get for this cooler hooked up to a 3700x? 

 

Thank you!

Most thermal pastes from reputable brands (EK, Arctic, etc) are within marginal differences of each other. As long as its applied correctly, you should have no issues.

Even if you purchased a $200 thermal paste, if used incorrectly, it will still be garbage.

Gd900, you can get a 30g tub of it for ~3$ and thatll last you a long long time

 

Arctic mx4 is also good but its also quite abit more expensive while being similar in performance to gd900

Best pastes right now for reasonable money are Kingpin KPX and Thermal Grizzly Kryonaut (or Extreme if you want to spend a bit more).

 

Arctic, EK and Noctua are ok too but below the above.

I have switched exclusively to Kingpin KPx, this is after years of liquid metal and noctua nt-H1. Between liquid metal and KPx I only lost 1-3C on load for GPUs, CPUs probably won't see much difference at all *unless you start lapping and manually increasing contact surface and decreasing IHS thickness*

I like SYY-157. Its cheap and works well. Thermalright TFX is the best I have used so far.

Or another cheap one from China: https://www.walmart.com/ip/ALL-GQ-5-10g-Thermal-Conductive-Grease-Paste-for-Processor-CPU-Heat-Sink-Plaster/707940318?athbdg=L1700 

14.3W/mK supposedly. Ordering from Aliexpress the price is considerably lower actaully.

 

Of course there is some paste that is reportedly 17W/mK but who knows how good is it in other aspects :
