Overclocking fun! - Radiator in icy water

[AstroBenny]

I was thinking about messing around with overclocking for fun with a g3258 and H100i cooler. I was wondering whether anyone had tried submerging the H100i radiator in icy water to lower temperatures

Obviously without the fans!

How would you keep the water cold

[Levent]

there is a reason why people dont do that, condensation.

Every 10min put some more cold water in.

Only the radiator would be in the water....

To me it just seems.....pointless, but if you really want to go ahead I guess.

piping would create a condensation, CPU block will, basically you would have to isolate everything with thick material.

there is a reason for gigantic isolation on the piping of phase change coolers.

If you want to get a stable overclock it would be too hard to keep putting your rad in water to cool it down every 5 mins while trying to use your computer. Just overclock it to a point where you have below 85 degree temps on full load.

A better solution is to hock your system up to a crane that got cold water in an just let it run.

It will effect your water bill, but at least so does the water not heat up as it goes to the sink after just 1 pass.

Only on my 5960X has chilled water led to a significant advantage.  Haswell-E seems to be very temperature sensitive in my experience where you're fucked if it gets past 85C (in terms of passing stress tests, not talking about lifespan).  Every degree below ambient gives just a little bit more headroom to allow for more voltage.

 

Haswell and Ivy (4 cores) chilled water was kinda pointless except to make my office silent.

 

The radiator will probably end up rusting if you leave it submerged too long.  Before I did heat exchangers, I submerged radiators, and this was the result:

 

 

The fins and chambers are copper / brass, but the casing is steel.  It's mostly a cosmetic issue though.

 

And if you go too cold you'll get condensation all over the base of the waterblock.  I've had my entire desktop looking like it was a rainforest in the case.  It's not fun.
