I used a Xigmatek HDT-RS1283 with Arctic Silver 5, and put a small line of TIM on each exposed heatpipe. I'm using a custom Cooler Master fan with the Xiggy heatsink, works marvelously. This is in a Xigmatek Midgard W case, the cooler is blowing up towards two exhaust fans. All frequencies were tested with Prime95 for 30 minutes to an hour, so I haven't confirmed if they are 24/7 stable. Temps were measured with CoreTemp. If you're getting better temps, let me know what you do!

Can you do a push pull with the xigmatek? I did so with my Tru and shaved off 2-3C.
With my tru and my X4 940 @ 3.5 I get about 35C idle and 50 load, but I don't need extra voltage which is why I like this OC for 24/7 operation.
17x and 205 reference.
Well, I have 3.5 clocked at stock voltage, and there are 2 140mm fans about an inch from the top of the heatsink, and they work pretty good to pull air. And yeah, that's the clock I run most of the time. =) Strange that your idle is lower but load is higher... I wonder if that makes a difference.
