I bought one of these Intel CPU coolers about 3 years ago, RTS2011LC for my Asus P7P55 Mobo. At the time it was quite an improvement on air cooling (Hyper 212) when overclocking.
I later upgraded to the ASUS P8Z77V-De Luxe and fitted the cooler to that machine.
My PC is usually running 24/7, and with a moderate O/C 4-4.2GHz.
Now recently, (last 3 months) I had noticed that the CPU fan was getting louder and louder and first assumed it must some garbage running in the background. After checking and running the usual Malwarebytes Win Defender Etc. I found no problems.
It was at this point i checked the CPU temps and this is where it starts to get interesting; ASUS Suite, reports the CPU temperature at about 65C, which is about 15 degrees higher than I would have expected given what was running. I then checked Real Temp and it showed almost 78C with the same load (not more than 20%)
I then decided to re run Prime 95 as i had a good idea what sort of temps. I used to get before (85C or so)
When I ran Prime, ASUS reports 84C and holding steady, OK I thought until I checked Real Temp - It was showing 105C on all 4 cores and the CPU was throttling back to 3.2 GHz!
After fiddling around for a while disconnecting various fans on the MB it appeared that the CPU fan on the Intel radiator made no difference to the temperatures whether on or off - the coolant pipes were as expected, on hot and one cold.
I checked the temperature of the fan output and it was cool rather than noticeably warm as it used to be.
Well, today I removed the cooler and there was barely a drop of liquid in the darn thing, it was just pumping air.
I understood these things were supposed to be good for at least 5 years and maintenance free, obviously not in thi case.
I dunked the entire system into a tub of hot water to pressurize it to see if there were any leeks, nothing to be found!
It would appear that the liquid must have somehow evaporated.
So if any of you are running the Intel cooler for an extended period and your CPU temps start rising gradually at first, it might be worth checking out.
I am going to drill a hole in the Rad and see if I can top it up, maybe fit a small refillable header etc. (as an experiment)
I bough the new Corsair H100i today and chopped a few chunks out of my case and managed to get it running - 4.2GHz and 39C - boy this beast knocks the spots off the Intel. (75C @ 4.2GHz on Prime 95, all stock voltages)
Hope this might prove helpful to someone in the future - Also, keep an eye on ASUS temperature monitoring from AI Suite, it never rose above 84C despite the core temps being 105C, not a good feeling with that as a safety net.
