Stuck on case-how many fans for cooling an i7920

I used a lian li pc-60B plus II for my 1st build & liked it, that was with a quad core q-9550 cpu.

My next build will be with a i7 920 & am concerned with the cooling capacity of that case ( 2-80mm's & 2 120mm's). It does fine with the quad core but I'm not so sure with the i7.

I've been looking at the lian li PC-K1B or PC-A6010B which both have 1-120mm & 1-140mm.

Does that fan config offer more cooling capacity than the 2-80mm/2-120mm's on the 1st case?

Would 1 120mm & 1 140mm be enough for the i7?

below are my parts excluding case, having a devil of a time deciding on the case.

  1. I couldn't help but notice that a lot of the Lian Li cases have one case fan at the bottom front and one case fan on the rear panel. That's quite different from some of the cases with lots of fans. It would be interesting to hear from actual Lian Li owners.
  2. yeah, the 60bplus that ive got has the 2 larger 120;s as intakes on the front & side & the smaller 80's as exhaust on the top & back.

    cpuid shows 27c for cpu & 35c for system with that setup but i think the i7's generate a lot more heat, not sure, never had one.
