HY510, K4-PRO &
K5-PRO Thermal Comparison
In today
article I will discuss 2 different brand of thermal paste I bought, their claimed
performance and product property, finally my test bench result and final
conclusion. Before I started the science experiment, I have to say I totally
regret to purchase the “K” series product and I will tell you why in the following
paragraph.
2 different thermal paste I purchased at the different time, both
purchased on ebay and their shipping and delivery time around 30days arrived my
door with the good packaging. The product property and thermal conductive
performance of K series thermal paste is mention on their website. K4-PRO has thermal conductivity K>4.6 W/m.K and K5-PRO has thermal conductivity K>5.3 W/m.K both are no electrical conductivity,
they also claimed the thermal conductivity is 3 times higher than common
thermal pastes and pads.

HY510 has
thermal conductivity of K>1.93 W/m.K but did not mention any information about
electric conductivity, however, tested the result is non conductivity as well.
Product property stated at ebay as well. http://www.ebay.co.uk/itm/HY510-30g-Grey-Thermal-Conductive-Grease-Paste-For-CPU-GPU-Chipset-Cooling-UK-/192120683326?hash=item2cbb48fb3e:g:4ccAAOSwCU1Yu3NT

After I introduced the product information,
this is the test bench information I should give for better reference. CPU = E2140
1.6GHz, stock heatsink crew mounted method. Motherboard = Gigabyte G31M-S2L. RAM
= 1GB 667MHz. No PCIe and No PCI in use.
Started the testing at room temperature
around 28-29°C with well air flow condition during summer night. Stress tested
the CPU by using HeavyLoad application to run about 10minutes for each test.
First, without unscrew anything on my test bench, the current thermal paste at
the time was HY510, so I ran HeavyLoad at the first time, ended my first test
of HY510 = 63°C.
Unscrewed the CPU heatsink, had a looked at
the CPU and heatsink surface, the paste was spread out very well covered,
greasy and easy to remove thanks to its silicon based. I cleaned up everything
by using Polylab contains alcohol 95%.

Second test, I applied K4-Pro to the CPU, ran
the same test again. Ended my second test of K4-Pro = 69°C.
Unscrewed the CPU heatsink, had a looked at
the CPU and heatsink surface, the paste was spread out very well covered and
this time it was so thin thanks to the low viscosity but harder. After that I cleaned
up everything by using Polylab contains alcohol 95%.

Test No.3, I applied K5-Pro to the CPU, ran
the same test again. Ended my test of K5-Pro = 72°C.
Unscrewed the CPU heatsink, had a looked at
the CPU and heatsink surface, the paste was spread out very well covered but it
was thick due to the high viscosity for thermal pad replacement and it is
harder than HY510 as well. After that I cleaned up everything by using Polylab contains
alcohol 95%.

So, why am I
regret? I paid another RM40 for a lower performance item! I spent 1.5 hour for
this experiment just to make sure if there was other factor cause the
unsatisfied result, in these tests, the HY510 the lower cost item completely
stand out. Why HY510 has lower thermal conductivity than K4 and K5 but has a
better performance?
So why HY510
has lower thermal conductivity than K4 and K5 but has a better performance?
K5 Pro is NOT even meant to be used with CPU's, but GPU's and chipset chips to replace thermal pads!
ReplyDeleteI would not call this a test...

People who worry about what thermal paste that they're using are a bunch of NOOBS! Anyone who's been doing this for awhile knows that what could be called the best and what could be called the worst will be LESS than a 7C difference! Who cares about a 7C difference on a CPU that can easily tolerate 80C under load?
ReplyDeleteJust save your money and get whatever the best price on purpose-made thermal paste that you can. If you're a professional overclocker and are sponsored by Arctic Silver or Thermal Grizzly, that's the ONLY time that you should use it because you're getting it for free and with pro overclocking, every degree counts.
If you're using this for your home/gaming rig, just get the cheap RY-510 and use it. If you're unsure, it's because you're a NOOB and have never done this before. Trust me, Kryonaut is so over-hyped simply because it gives, on average, a 3C (yes, THREE DEGREES) lower temperature than your average, run-of-the-mill paste that OEMs use like RY-510. I bought 30g of the stuff for UNDER $5CAD while Kryonaut costs about $12CAD for 1g. How much of that do you think is nothing more than PURE PROFIT if a company can profit by making and selling a competent thermal paste like RY-510 for less than 20¢ per gram? I'd say at least 95% of the price of Kryonaut is just profit.
DerBauer is sure getting rich with Thermal Grizzly, eh?
Yeah, there's a new article on Tom's Hardware that says something similar to what you said:
