They're not great but I would say tolerable. I haven't done any real testing. I might soon because I want to see what this Asus cooler can do. Just haven't had time to do a proper overclock.
You noticed that too! Yeah I didn't notice it until the 30 day return period was over. Assembled incorrectly. I've been meaning to contact inwin about it but have been just too busy. I'm not sure what happened there I certainly didn't modify it.
