Actually, I have block #8 of the "Window" version (ordered a full copper but he Upgraded my order). I had been using an aluminum block and a copper based block (looks like the polyblock but home made) and the temps went down to an idle/surf temp of 103F in an 84F room...on a T-Bird 1.2 at 1.4 something (vid card doen't like the 1.5 plus area). I was seeing 125F with a WBK38 and around 116F with my version of the polyblock.
In other words..I am very glad I made the purchase (first time for the web). I got it mainly because I was following the threads when fixittt first started posting the design and thought that it HAD to be good.
It weighs a TON however. I switched from nylon mounting bolts (four hole mount on motherboard)to the steel ones as I was sure the weight of the block would break them! It is very heavy. I can't compare it with Dangerden or any others for you But can only say I am glad I bought the Spiral block. Fixittt did state that the blocks were unlapped and you would need a little bit of time with the sandpaper...I spent all of three minutes sanding, used radio shack goop and am very happy. Sooo, I really hope the review comes along soon for those who are in agony waiting to see which block to get, be it Fixittt's or Dangerden or other.
