Cpu was acting up!

So I have an i7-5690x OC'd to 5ghz, so it generates a lot of heat.

Now I don't remember exactly how I got it.. I think it was a freebie because I bought so much.. anyway I had this 'thermal paste tab'. So instead of smearing the CPU with thermal paste; I just attach this little tab and all is well.

Roughly 6 months go by and I had no troubles and then all of a sudden my cpu temperatures would jump up quite drastically. So I did the usual PC maintenance by clearing out the radiator fans etc and temps were still very.. spikey

I had some free time so I removed the glass lid, lift off the water block and this is what I find-- HAHA

Yeaaaaaaaahhhhhhhhh.
Figured someone might get a cheap laugh out of it.
