Old Crosair h100i. Unusally high temps

Blockage or has all my water finally evaporated?
Got this baby when 4690k came out so its pretty old.

I feel i used to be aable to hit 4.7G @ 60c.

Now my temps are everywhere and i cant run cbench15 with out crashing. temps go to 90c fast.. then hit 100c.

15c difference in cores at time.

About to go to ace hardware get some hose clamps and take it apart see how much water i got.

Push pull, ambient temp is like 13c-18c Sometimes 0c if i stick the rad in the window (live in cold as **** wyoming)

Was it running ever since you bought it or had you put it in the attic for a while?

Always running. Intel braket is mounted correctectly. Ive done the washer method and without the washer method(a little jiggly backplate)

I've reapplied as5(only thing I can buy out of a store thats not 2hrs away) with the line method(as instructed by the instructions via as5 and my cpu) and pea method after the line didnt work.

something weird happens to the oily coolant inside of them. idk if it congeals or what, as I've never busted one open. However, my brother and I both had the same type of failure on our original H80 and H100 units (not i)

old = ?

a year? 5? big difference. every AIO is going to fail eventually.

Possibly 7 years old.

You've got liquid with chemicals inside, plus mechanical parts. They're bound to expire or fail after some worked period.

Oh yeah I know. I didnt hear any air bubbles(when pumps start pushing air) tho so I was more concerned that I warped my IHS and maybe thats the reason?

Anyways I cut the black hoses removed the rad went and got some tubing and an fish tank pump.
Filled my old fish tank with rain-x and its on the porch keeping nice and cold (0c-10c) and connected it to the block. at least I was able to finish cinebench this time.. got max to 81c which im ok with this ghetto rig until i upgrade in november.(was hitting 104c and shutting off)

The fish tank pump isnt over working the pump in the crosair block and all flow is going same way. Figured I got 4ft of hose so needed a lil extra pump.

I just think i have a warped IHS on my 4690k and just cant get good contact.
Core1 is always around 30c while the other 3 or 16-19c with a 3%load. Core 2-4 also never go above 60c in cinebench so yeah. I unno.

Thanks for the reply.

Liquid inside was tinted yellow. No specks no gelation. I did take the block apart tho and noticed some lime build up maybe inside the cooperblock.

You can delid your i5 too and replace the paste inside.

If you warped your IHS, the whole cpu would be bent. You really can't warp it at the temps where your pcb wouldn't burn to a crisp. I had an old coolermaster aio (3 or 4 years old) half/mostly die. It started getting high temps like yours, I replaced it and everything was good again. I kept it around and tried using it on my daughter's computer. It worked again for a little bit and then started performing like yours again where it cooled at a fraction of it's previous potential. Also you seem like the type that would find delidding your 4690k worth it.
