Nah...
While I am interested in a SLK-900 vs. MCX4000 shootout, I do not ever think I am going to try Thermalrights cooling products after making some 1U server computers.
While they might offer 1º or 2º C difference in cooling in either direction(?)... I can not bring myself to wanting to buy their products again for my own use.
However when I build computers for other peeps, some are brand religous. It would be nice to know what the SLK-900 does before I recommend a different cooler unless they absolutely insist on Thermalright.
As it stands, the Alpha 8942 is still king on higher end air cooling for the P4's on price/performance. But I am in need of slightly better temps as the IHS removal will not be that much of an option unless I decide to keep a chip for a year or so...
