Its interesting because the reps are paid by Corsair to comment/troubleshoot problems and provide advice. They do spend money to do exactly that...to comment on their products...to make sure they maintain their image...which has clearly been lost on you too!
If you post in another section, for example - Graphics, the reps do a good job of making sure that at the very least they have acknowledged a problem.
On a separate note, why was your RMA painful? Mine seems to be quite straightforward...they have taken my CC number, will send me a new cooler and I send the old one back! My CC doesn't get charged as long as they get the old one back within 2 weeks.
I couldn't see the option to get a replacement before sending my old one off. It was at this point I thought F it, bye bye Corsair. So I bought a Noctua DH15 to replace the H100i. My 4790K idles at 27-30 degrees and under load I've seen it get up to high 50s. But this isn't an AIO vs Air debate so I'll leave it at that.
Sent my H100i off (I had to pay for postage), had no replies to my ticket (even though I posted questions) until about 2 weeks later I received a DPD note through my door, explaining that my parcel would be ready to collect the next day...
Great, but they missed out the bit where I should be collecting it from.
So 15 minutes calling 0845 numbers later and I've found the shop I need to goto (only 2 miles away...) and I go there the next day. The lady in the shop has no idea what's going on- I explain I'm picking up a parcel, show her my delivery slip and she says I need to print my email... lol.
Anyway, after a bit of sweet talking we agree that I can take the box with my name and address on that's behind her home with me.
Open it and it's a sealed brand new H100i. So not a terrible ending I suppose. Means I can throw away the rest of the stuff I didn't send off and stick this one on eBay.
Not a great experience. I've had SP2500 go wrong 2 months out of warranty and Corsair basically told me to 'do one'. Sure a lot of people have Corsair stuff that doesn't go wrong, I won't be chancing it in future though, high end or go home IMO.
