CPU (i7-4790k) overheating, questions about what the problem could be (water cooler broken? Corsair Hydro h110)

Hello. So about a month ago my computer started crashing almost daily if I played games like WoW or Divinity Original sin. I've been using CoreTemp for almost 3 years now, and I noticed that while playing Divinity, while having literally everything closed except skype to speak with my friend, the temps would go to 80-95 C and my computer would shut down. So, after this I looked for possible help from friends and internet, so first things first I bought Coollaboratory liquid pro thermal paste, cleaned my PC off all dust for a good 2 hours, cleaned off the old thermal paste with isopropyl and added the new thermal paste. I noticed that the temperatures had lowered a bit, now my idle temps were around 35-50, and while I played Divinity (once again, with everything closed except the game and skype) the temps would go to 70-85, and my computer wouldn't crash. However, this only lasted for like a week or two, and now its back to the same 85-95 C and constant crashing. So I'm a bit baffled here. I started googling about the water cooler I have, and I'm suspecting that the problem would be there. However, I'm not sure how to identify whether the water cooler is actually broken or not. I bought all the components to my computer in the summer of 2014 and the water cooler has a 5 year warranty, so I can RMA it, but I first want to find out how I can know that the problem is in the water cooler (so far by the process of elimination I've leaned towards a broken water cooler, but I don't think thats a good enough explanation if I RMA it lol.) Also I checked that my fans are working and running at full speed, and indeed they were.

So here's my computer specs once again:
cpu: i7-4790k cpu @ 4.00 GHz
gpu: nvidia gtx 780 ti
water cooler: corsair hydro h110

Thank you in advance!

  1. IS your Water cooler a Closed-Loop? I am not familiar with that brand.

    Nah I really dont know anything, thats why im asking here. How do I check something like that? Just try to listen or use some program?
  5. have you looked between radiator and fans ? there could be a lot of dust.
    have you tried to download and use corsair link ?
    the main thing you want to look for is pump speed.

    i mentioned in the post that i had cleaned my computer fully and checked the fans. their all clean and working. i downloaded corsair link earlier to look for that exact thing as someone had already suggested it to me, but the program didnt show it for me, or then im just an idiot and couldnt find it. if you have, could you provide me with an SS of where I can look for the speed of the pump on corsair link?
    thanks in advance

    edit: here's an SS what mine looks like http://puu.sh/w2HH8/58a3311fe4.jpg

    Did you resolve this? Chances are your connection isn't plugged into the USB header on your motherboard. Hence its not displaying in Corsair Link. As for your problem... sounds like a faulty pump. Would love to confirm this in the software however.
