Water Cooling Fluid Degrading?

[el_guapo3291]

Hi Guys, just have a question that has been bugging me a bit... I am currently using EKWB Cryofuel and I filled it into my loop (Which consists of an xspc photon reservoir, ekwb d5 pump, ekwb supremacy evo cpu block,ekwb gtx 1080ti gpu block and 2 X 480mm rads) in around the first week of July in 2018. I keep my radiators very clean and they have no dust build up, yet I notice roughly every 6 months my loop loses its performance (When I flush and put in new fluid CPU max temp = 55-60c and GPU = 38-45, after 6 months CPU temp = 72+ and GPU = 60+ , these are measured in a temperature controlled environment so ambient temps are the same).I had the same issue previously and I am starting to think it may be a problem with EKWB cryofuel, but they rate it to last 2 years so surely it should not be losing performance in 6 months?... Also there is no build up of residue or blockages in the loop, my blocks are absolutely clean! so is it possible that the cryofuel is somehow degrading over time? but its just a fluid? what could be changing in its composition to cause such a dramatic loss of performance???

Looking at your dates, July = Winter, January(6 months later) = Summer. Ambient Temps play a big part in operating temps. Liquids retains heat, so check what the idle temps are also and see what the delta temp is. Using max temps with water-cooling doesn't work well, delta temps give you alot better data. Water temp sensors also helps.

You need to flush and clean your loop/Blocks/Rads every 6-12 months . All these fancy coloured fluids will always leave deposits esp in the blocks where the fine cooling fins are. All of them claim to be different, but most times they fall short. You need to clean your radiators , especially when brand new, alot of flakes are in them.

What do you guys use to clean your radiators?
Special tools or procedures needed to clean it properly?

I remember 3D Guru had a test of the effect of delta temp for air cooling.
If the delta is up by 2 degrees the card run as much as 4-5 degrees hotter than normal.
So winter temp should be measured with same season temps.

The room is climate controlled so same temperature & humidity all year round. I stripped everything yesterday and micro fins were absolutely perfect. So still have no idea what causes the problem but going to try something different to cryofuel.

I mix distilled water and white vinegar at a 1:3 ratio. Run it through the rads with a spare pump that I have for about an hour then drain it. Then I flush the system with some hot distilled water and then finally run it with the spare pump again with cool distilled water before draining and fitting it back into the PC.

I still think Delta temps is the way to go. Also a temp sensor to measure water temp will help greatly in this investigation. Maybe even a flow sensor so you not guessing if there is a blockage or not.

Try using de ionised distelled water as well
