Recently had a heat problem in my system, I thought it was my thermal pasta because the block had come off the cpu a bit, after opening eveything up I released the pump wasn't moving any water, I figured it was airlocked, I took the pump and moved it below the radiator and let it go for a few seconds. Now the pump doesn't work at for some reason. I have no idea what I did wrong or even if was something I did. Any suggestions would be helpful.

I went back to air cooling for the time being.

You can disable the voltage throttling in the BIOS. This will force a constant voltage to be applied to the fan header and thus your H80i pump will stay at the same rate all the time. You can then plug the 120mm fan into the second fan header and have that regulate fan speed by CPU temperature. That's how I have my H110 set up and it works perfectly. As for why no one talks about the H80i Link software, I'm not sure I can answer your question. I guess it's because no one brought...

if by chance it was air bound and the pump wasn't "submerged" it could very have well have died. that's how it stays lubed.

you can't tighten one screw down and then go to another. you have to gradually screw in each one so the block goes down evenly.

and if you didn't attach it to a fan header, but to the cpu header, the pump wasn't running at a fast steady rate like it should have been.

But it failed as I was letting water back into the pump? that doesn't make sense to me...

I didn't screw them down tight one at a time, they both went down gradually. Over the months the little plastic tabs warped from the heat and caused it to be loose.

I did attach it to the cpu heater, I didn't know it was suppose to be hooked up to a fan header but that does make sense.

My H80i pump also failed after about 5 months. One day I noticed CPU temps were in the 80s Celsius, then once it hit 90C, my system shutdown due to the BIOS TDP protection. I had to RMA it to Corsair, who eventually sent me a brand new replacement AFTER they received and inspected the defective unit. I was told the wait time was 2 1/2 weeks, so I bought a new H80i and then sold the RMA replacement to a friend. I never had any problems with the second unit, so the first one failing was most likely a rare "lemon".

This is what happened to me. Was running perfectly fine, there is no way air could have gotten into the pump. My computer was get to the TDP just surfing the web. I'll see what I can do about RMA.

Did you purchase online or through a local retailer? Obtaining your receipt from an online retailer is quite easy. Getting one from the local retailer may be a bit more difficult. If you did purchase the H80i from a local retailer, go to that store and ask the customer service if there is any way they can provide you a receipt of the purchase. If you used a debit or credit card, they will most likely be able to pull up the purchase receipt record for you.

I bought it online I just can't remember where from.

I decided I was going to check if it was really dead or not, so I dug out my spare PSU, plugged it in and the pump fired right up and is moving water... I don't know whether to give it another try in my machine or just leave it out and stick with the air cooling

Try using a different fan header on your motherboard. Either the fan header you were using has gone bad, or you need to change the fan speed setting in the BIOS so that sufficient power is being provided. The instructions for the H80i state that you are supposed to use the fan header designated for the CPU, so try that one first.

Should you use the Link software? I would say yes if you want to get the most out of your product's performance and capabilities.
