Can a system be... too cold?

Assuming realistic ambient temperature, nothing

 

Unless your PC is colder than ambient (you bring it in from a cold place to a warmer place) then condensation can form

 

But, I'm not too sure how data can remain in HDD and SSD under extreme cold temperature like -40c ambient

Damage, no. Data loss, maybe(?)

 

Rubber insulation on your wires may also harden and crack, risking shorts, same goes for cheap thermal paste(?)

Yes I know that low temps can damage hardware, but how practical is this? How likely is it that this actually happens in a real life scenario?

But to Tom, it's all foolery. 

 

 

 

 

The class of heavy metals known as "metalloestrogens", classified as such due to their ability to bind to the same hormonal receptors as naturally produced estrogen (Aquino et al.), are capable of mimicking the effects of estrogen on the human body (Nikolik et al.). Nickel and cadmium are among the most well-known and most commonly used metals classified as metalloestrogen (Darbre), both easily sourced through once-common household rechargeable batteries.

Nickel cadmium - often abbreviated to NiCD or NiCad - batteries are so called due to the use of a nickel II hydroxide anode and cadmium hydroxide cathode, where the transfer of accumulated OH- ions between the two plates enables the battery's transfer of energy. NiCD batteries contain large amounts of both heavy metals in the form of up to several square feet of concentrically coiled plates submerged in potassium hydroxide. Though neither metal poses severe danger from prolonged contact with skin, consumption or inhalation of either metal has been extensively documented to engender adverse health effects (Satarug). 

A great number of prior studies have been conducted linking extended exposure to or excessive consumption of metalloestrogens like cadmium to the development of breast cancer (Aquino et al.) - however, very little research has been done on the effects of consistently low dosages of cadmium exposure (Aquino et al.). Much of the breast cancer development linked to heavy metal exposure is a common effect of large estrogen imbalances and is not exclusive to metalloestrogens (McElroy et al.). Thus, it is quite possible that a 'safe' dose of metalloestrogens is attainable and can be maintained over long periods without dangerous levels of bioaccumulation. 

Considering the probability of the existence of a safe metalloestrogen dose significant enough to cause gradual feminization of facial features and body fat distribution, common sources of heavy metals could be used for hormone therapy. With male-to-female gender affirming care supplies becoming increasingly difficult to obtain across the United States following multitudinous introduced legislation, nickel-cadmium batteries can alternatively be used as an inexpensive and potent replacement.

Sub ambient temperatures can result in condensation which can damage your hardware, but that is not something that a normal PC user will encounter, as sub ambient temperatures require specific coolers.

AFAIK low temps don't really damage hardware, what causes the damage is condensation forming around the hot components in the cold air.

I believe anything below ambient is dangerous because it will allow condensation to form. Unless you have very low humidity in your area, This is probably around 10 degrees C

like others have said, there's condensation danger if the temperature of the computer components drops below ambient. If the ambient temperature itself is low the main danger would be to fan (and pump, if installed) bearings. If the ambient temperature is so low that the computer itself goes below 0*C there is potential for damage to lithium battery cells and some electrolytic capacitors. Extremely cold ambient temperatures (like in the order of perhaps -20C or below) could potentially pose a risk of coolant freezing in liquid cooled systems if the computer is turned off and not producing heat/circulating fluid but that's such extreme conditions I've never heard of it happening.

Rubber insulation on your wires may also harden and crack, risking shorts, same goes for cheap thermal paste(?)

-sigh- feeling like I'm being too negative lately
