KY Jelly Cooled PC

Recommended Posts

Posted · Original PosterOP

When I was stationed in Okinawa, Japan, I took some courses with the Marines Corps Communication-Electronics School (I was Air Force). During a course the instructor told us that KY jelly was invented by NASA to cool off their rockets, shuttles, etc... I cannot find any information to confirm that, but since I've seen you guys build mineral oil and liquid rigs why not test KY jelly and see if it works!

I've never heard that one before.

KY jelly was originally made for surgical purposes in the early 1900's.

It's basically just glycerine and glycol. If thinned It would probably make for a pretty mediocre coolant compared to water and may not function at all in any loop just due to its viscosity if not thinned.


Pro tip, before you reply to an question or topic, answer these three questions:

 

1) Do I actually have an answer for OP at all?

2) Am I giving an answer that is based in multiple reliable source tests and not personal opinion or heresay?

3) Is my answer on topic, clear and concise?

 

If you answered "no" to any of those, close the tab.

Do not give people information you personally think is correct. Source, research and then reply. If you plain and simple don't know what you're talking about, don't talk about it. It's harmful to support questions on forums to be providing people with wrong or misleading information. As well as going off topic from the original question.

i.e. "What B360 motherboard should I buy?"

>someone replies with a PC partpicker list with a ryzen system

Not what was asked.

what in the world 

i dont think so 

mineral oil works because it has a high heat capacity, like water 

Ky jelly would be too viscous to cause turbulence, and thus heat transfer would be abominable

your instructor lied to you, sorry

also based on some rough google searches, it seems, it was used for high temperature lubrication, and not cooling per say

once heated the product becomes less viscous...its thick because its in a bottle at room temperature and not even that...its always at store A/C temp. additionally, there are other types of the same product that are more liquid. besides, the episode Chilling Threadripper 2, Linus used Rain-X to chill a CPU...it contains among other things glycerine and glycol.

yeah sure but again its not as viscous, even if  the viscosity changes to a usable amount at like 60-80 Celsius ,what advantage does it give over water

the reason linus uses rain x is because it works well at low temperatures

I enjoy coating my rocket in KY jelly prior to liftoff.
