had the same issue.
both the IHS and the schyte ninja was not flat, lol.
easier to flat the schyte though.
dropped 10 degrees so consider that good since there was little contact.
just gonna see when waterblock arrives if there is a need to lap the IHS.
I have just a few things to add before I leave this dead-horse subject.
1) My apologies to JayG30. I could have phrased my disagreement with you in a much less offensive way. I just got over the flu and was cranky last night. My bad.
2) Many of those arguing how "crappy" their IHS was and how lapping proves it was concave are overlooking a very important detail. When you lap your IHS it is not subject to a ~40lbf heatsink load, unless you're applying ~40lbf pressure to it (and likely warping your plate glass sanding base), and if it were, your IHS flatness would most likely be quite a bit better.
4) This is the same old argument that started with the first IHS-shod P4s and back then everyone complained that their IHS was concave. Well, it is until you apply the heatsink loading to it. That's how it's designed to work. Whether it works correctly everytime is another matter.
5) Apparently there must be some truly out-of-spec IHS out there but I think it's getting out of hand when the recommended solution to every perceived high cpu temp question lately seems to be to lap the IHS.
6) I'm glad that some of you are happy with the results you got from lapping but it's just a little hard for me to understand how so many can be getting ~10C temp reductions when I've owned or built at least a dozen Intel systems with IHS and not one of them required lapping or benefitted more than 2C from lapping and all but 2 of these were higher-power Netburst CPUs.
That's all folks...
This thread didnt have to turn into such a flamefest. If there are owners that feel that intel messed up and didnt intend on their ihs to be concave you can do as some suggested earlier, rma or even better if your so inclined lap away.
Its your product your free to do whatever with it. The only thing thats hard to believe is that everybody is getting 10C drops in temps across the board.:stick:
Some others have their theories on why the ihs on some conroes are intentionally concave and they are entitled to their opinoins. But the bottom line is concave or not, their are alot of people overclocking the hell out of these cpus and dont seem to be bothered in the least by the damn ihs.
I also think theres a population that doesnt understand that if you pump 1.5 plus volts into a conroe and cool it with a scythe ninja or thermaltake big water kit. Your temps are most likely going to suck:slapass:
Now lets all get in a big circle, hold hands and sing kubaya. :)
