Corsair Issues Warning of H100 Fan Controller Issues

Over the recent days, Corsair has seen a growing number of complaints on the fan controller on their Hydro Series H100 CPU water cooler within their forums.

Corsair has acknowledged there is an issue with some of the components included in a small number of H100 units with lot code 11359403 only. You can find your lot code on the printed label on your H100 box (See below image).

The issue seems severe enough that you are seeing the H100 being removed from the store shelves (as a sign of a partial recall by Corsair). Taking a closer look at the issue, it is related to the button on the unit that changes fan profiles. On affected coolers, the fan works at the default speeds no matter what the selected profile is.

Corsair is recommending "if you have this lot code, test your installed unit while the system is running by pressing the profile change button. If you push the profile button on the top of the cooling unit and the indicator lights change, but the fan noise remains the same, we recommend contacting Corsair technical support at ramguy@corsair.com to arrange for some replacement parts that will correct this problem."

    As a quality parts brand name I expect Corsair to fully back the affected units. That's why I buy their products.

    Is it just me or is Corsair's quality going down hill recently?

    Hey, I'll tell you what. You can get a good look at a butcher's ass by sticking your head up there. But, wouldn't you rather to take his word for it?

    "I can take a crap in a box and stick a warranty label on it. All it means is you have a guaranteed piece of crap."

    Good for Corsair to make right on their products. Some other un-named companies would rather give out plastic bumpers as a free bonus item, rather than admist there is a problem.

    I think the products that Corsair puts its logo on are great. They typically just work... I'm glad to see that in this instance as in times before when there is a problem with a product of theirs the biggest concern for them isn't, "How much money will we be losing?" They are concerned more with maintaining their well earned reputation.

    Aww crap i think mine might be in this lot. I've haven't noticed the any fan speed increases on mine, other than when i first boot up my pc. Guess i'll have to check once i get back home.
