I dissected my 6 year old 240mm AIO

[Chuckmiller1964]

From what little I know about it the coolant fluid looked fresh. It was a clear medium green color, no solids at all, no odor. The fluid passage in the cold plate was spotless. I couldn't get to the pump impeller because I didn't have the triangle shaped tool tip. It had 150ml of coolant fluid.  Was it still full? I don't know. Was it still capable of cooling at full capacity? I don't know. When the i9-9900k (running a mild OC) was at full load I could feel significant heat coming from the radiator. I don't have an infrared camera so I cannot look for hot/cold/flow in the rad.  

 

Has the thermal paste held up for 6 years of nearly 24/7 on time? I don't know. It's still soft.

Paste looks good, when its questionable is when its flaking and so dry that its no longer fluid like.

 

I've got an AIO that's either 9 or 10 years old (I bought two around the same time, don't know which one this one I have left still cooling a 4790k is). Its still running strong when I last tested it a couple months ago, so they hold up far better than most people expect. This one in particular also went through some extreme hot and cold cycles being in storage over the years. Its even been out to sea.

 

Can still maintain my 4790k cool and stable with a 4.6GHz OC. Can't say that for the 65mm Noctua air cooler I went to go swap it with though.

Share a pic of the inside of the pump and fins?

Similar with my ThermalTake Water 3.0, still keeping my 9900K cool at 5.1 all core for years now.  Think it's coming up on 7 years?

 

 

Yeah, 6.5 years so far...

I can't, the parts have been disposed of already.

The one I still have is either one of these. Way back in the day when spending $1000 on a GPU was considered insane.

Well done, sir. In order to know whether you're having temperature problems, you can:

• buy a no-contact digital thermometer, or
• install monitoring software like HWiNFO64 to monitor all the temperature sensors in your motherboard.

That way, you'll know if there's something wrong or not, rather than trusting the amount of heat you feel from your PC (which you should, especially if you're OCing).
