Hi,
I ordered a thermaltake frio last week, and I just tried to connect it to my new PC this weekend. Upon opening bag B, the mount supplied was not the correct one for the LGA 1156, it isn't even the same size as the other one it is paired with. You can download their manual here:
thermaltakeusa.com/Product.aspx?S=1319&ID=1956#Tab5
I have made an online request too, if you check that, then I will have some screenshots illustrating what the second mount looks like.
Please let me know what I can do, none of the other mounts supplied are the correct size, so unless I am missing something, then I have been supplied with the wrong parts. I would rather not go to the hassle of returning the whole unit, as all I am missing is a single component, but it looks like none of the shops will sell this on its own.
