AI Thread Summary
When lubricating computer fans, it's important to choose the right type of lubricant. WD40 and similar products dry quickly and are not suitable as long-term lubricants. While lithium grease is effective, its thickness can hinder proper application into bearings. Thinning lithium grease is an option, but caution is advised regarding the use of thinners or WD40 oil, as WD40 is not recommended for lubrication purposes. Alternatives like sewing machine oil or 3-in-1 oil are suggested as suitable options for applying a controlled amount of lubrication.

Hi!

I was about lubricating my computer fan. The WD40/sewing/machine oil dries up quickly so I was wondering about Lithium grease, but unfortunately it's too thick, and it won't flow into the bearings.

So I was wondering about ways to thin it. I read thinner is good, but can I use WD40 oil too? Finally it contains alcohol.

WD40 should not be used as a lubricant.

Sewing oil, or any of the other oils that come in a can to apply a drop at a time, such as 3 in 1 Oil, should be OK.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
