Hey guys, I just have been thinking if I can use WD 40 as a cooling liquid. What do you think ??

I'm just interested if it would work, at least for a while.

 

If you go by than logic then no cooling at all would work too, "at least for a while".

The solvent will quickly evapourate, leaving behind a small amount of oil. You can make it work if you used enough of it (a dozen cans of it might not be enough), and good luck cleaning up the loop

It may work for a very limited amount of time although I would not recommend using WD 40 as a cooling liquid as it has the potential to jam your loop to some extent over time which would slow down water moving through it and it is not going to be the most efficient as having the role of dissipating heat away from a computer system. The pump would have to work harder to move the same amount of fluid through the loop if you use WD 40 as being compared to using distilled water or any other good computer cooling fluid sold on the market today. If you are going to do it as an experiment then you can by all means although you have to accept the risk of damaging your system potentially.


Hope this information post was helpful  ?,

I would not suggest it as it is difficult to say what long term exposure would do to components designed for water. WD-40 (while not a great oil penetrant) will tend to seep into things which could cause problems. Unless you're curious what would happen and are prepared to lose components in the sake of your experiment, I wouldn't.

Now I could see the benefits here. Built in corrosion resistance very low surface tension so bubbles and foaming won't occur the stuff is a lubricant after all it's fairly inexpensive when purchased in a gallon jug only about $20 US and it doesn't conduct til 44,000 volts. It is not a solvent (as long as you buy it in a jug) the only thing that is the unkown here is it's thermal capacity and conductivity. Which even if it is lower than water let's say it has less surface tension than water and it is less dense making it overall easier to move not only prolonging the pump but also making it move through the loop faster which in turn causes better cooling efficiency. Just spitballing because it's properties seem very tempting. And even if it did leak, evaporate, or not work well the system would be completely fine just a lil slippery or it would turn off because of temp sensors.

No!!! It will destroy all the rubber gaskets in you loop. Unless you change them to oil/fuel resistant ones. The o-rings in the fittings can easily be chsnged to oil/fuel resistant ones, you can get them in hydrolic - automotive shop, but the ones in the waterblocks are not that easy to replace.

Nobody uses WD-40 anymore the performance boost was negligible, we've moved on.


Best & worst cases for your money in 2018 are:

 

Best Cases overall

 

I) Fractal Design Meshify C - Airflow and relatively quiet, best all around case

I) Phanteks Enthoo Pro M / Special Edition (white interior) - Airflow & full water cooling support

I) Fractal Define R6 - Silent with decent airflow

I) Be Quiet! DB 900 (Full Tower) - Airflow and silent 

I) Fractal Design Meshify C mini (mATX)

I) Corsair 400C - Only use with low end components, no 1080 / TI

I) Phanteks 350X - Only use with low end components, no 1080 / TI

I) Fractal Design Focus G

 

Cases that may be worth your money

 

I) Thermaltake G21 - GPU and CPU cooling issues, modest tweaking
I) Silverstone RL06 / Pro - Mustard/Ketchup wires, Shitty cable management, Poor front radiator support, useless psu filter, stupid ssd layout
I) In Win 303

I) Coolermaster H500 no suffix - if 200mm fans are your thing

I) NZXT H700 non "i" version - Needs to come down in price to be worth it

I) Corsair Carbide 100R - Suitable for low end builds

 

The worst cases - Do Not Buy

 

I) NZXT S340/Elite, H500, H440 (everything except the H700) Reason: Poor airflow
I) Coolermaster Masterbox 5

Majority of cases on the market

Ya know what I'mma do it anyway. What could go wrong my PC gets a little slippery? I think you have a little bit of a bent perception on wd40. I'm a mechanic, an electrician, a computer builder, and a little bit of carpenter in there. I've worked on hydraulics and operated large machinery all my life. I've never seen wd40 do any damage to any plastics or rubber in my entire life (I've been working on cars since the age of 3) and just to add a little salt to the wound car dealers spray wd40 on the engine bay the dashboard and wheels to make them look clean and shiny but never has it done damage as I've done it too! Now brake clean that's messed some shit up. Two days ago I used brake clean and sprayed down a keyboard that was a toilet for mice for a little while and it desimated the plastic. The keys were fused to the backplate and it was kinda sad but at the same time didn't matter as it was a cheap black widow board and mouse. Either way I think this thread needs to be ended by someone that actually tries it rather than speculates or talks out their ass. Wish me luck! Or not I don't count on it more than I count on my own intuition.... ? 

 

 

Edit

Ok so the results are in. It worked very well for cooling but there were a few hurdles to make it viable. You have to have very good compression fittings. If they are loose fitting for the tubing it will make the tube slide off. That was the only issue I had. If you are using Hardline you should have no problems. One other thing was it looked like milk which is pretty unattractive but for science I'll live!  I'll keep this thread updated

It wont work.  Wd-40 is a creeping oil, ie its really really good at getting through impossible openings.  Also it will evaporate quite quickly.

Use regular mineraloil instead if you absolutely have to.  Or just water and some brown-ish dye
