How do you prevent condensation?

post #1 of 40
Thread Starter 
At first I thought this was a leak after examining everything and having it on for hours there was no leak. Puzzled I just didn't know what to think. Just now I turned my computer on and this happened. Maybe 1 or 2 drips every few minutes so I'm guessing definitely not a leak. (Although all my barbs are on too tight they aren't causing a problem now so I don't want to risk it)


If this was a leak wouldn't it be constant? Not on and off...?


Temps:

Outside: 7.78c
CPU: 37c
GPU: 30c
Room: ~20c

Here is where it was leaking from right in front of this tubing out of the hole where a screw would go in the rad.



Here is my setup for context: (Towel and paper towel there because this is where water was last time)

if it was condensation it would most likely be on your tubes,mobo around the cpu socket and especially the waterblock,not just one corner of the rad,could you pull the rad and have a closer look?

not condensation.. condensation occurs when the item you're using is at a lower temperature than the ambient air temperature where the item is. Your cpu and gpu and loop are around 30s, and your ambient is 20 so you're not gonna have condensation unless you're running a TEC chiller or Pelletier

If you have condensation you need to isolate with foam all your blocks and tubes, otherwise unless ambient is 0% humidity, it'll from droplets and blow your computer up.

Having some dessecant (such as naftalene pellets) inside the case is always a good idea when doing hardcore cooling.

If it's only in your radiator barbs where it "condensates", it might mean that once your barbs have contracted due to the cold temperatures, they are leaking due to small gaps opened.

I'm pretty sure it is condensation. As it just doesn't make sense that I could run it for ~8 hours yesterday with no drips and today I get it. I don't see how that would be a crack.

I took all the fans off yesterday had a look at it and didn't see anything wrong. Shook it up a bit, nothing. And now nothing no drips. -.-

is it worth putting some ptfe and silicone on the barbs thread and outside of the barbs just for peace of mind?

Unless your water is running at a lower temperature than the room's air temperature, it is probably not condensation.
Take the barb off and apply some teflon, see if that helps.

So an O ring leak? Once the computer heats up I have 0 problems.

I will look into that first thing though...

It is 76% humidiity today.

And it isn't leaking from the barb. It is just forming near that screw hole and making a little water bubble. The outside area of the barb NEVER gets wet. Even the surrounding little bit is completely dry. I checked my screws on the fans there isn't in a screw in the screw hole for the fan above where it is dripping.

Second this, a tube of silicone for a caulking gun is pretty cheap.

I'd really rather not take everything apart again. Scary stuff. IMO

But if I have to I will but not for another week because I'd need more tubing and a plug for a t line which I forgot to order. >.<

I really don't think it is a leak. Because it is on and off on and off. First time it was A LOT. Like a pretty large size puddle on the PSU cover which is why the towel is there. But my heating was on like 70 and my window was wide open and my heating vent is right near the window.

So first time, a lot.
Then, nothing.
Now, 1 drop then nothing.
