post #1 of 7
Thread Starter 
Hello,

Im pretty new here but i been doing sum reading the past hour since i been logged on. I just purchased a BIG TYPHOON! and i was reading up on lapping. if i have it correct, lapping is the process of flattening the surface of the actual heatsink correct? and/or processor? im mainly looking for tips and ideas, and is greatly appreciated

Yeah, basically you're using fine sandpaper to reduce the grain of the metal. The idea is that more of the heatsink is in contact with the CPU, to aid heat dissapation.

The general consensus is it will lower your temps by a few °C. Personally I don't think it's worth the effort, but if it takes your fancy give it a whirl. It's very inexpensive and good if you're bored I guess

Hey guys, I just put the BT in and I used articSilver but I really have not seen any reduction in my temps. I run about 29-31C and 33-37c running online game like BF2. These temps are about the same that I was getting witht he stock fan. Any Ideas if I may be didn't do something right when i installed it. Also, is there anyway to increase the rpm on the fan?

Thanks.

i have lapped many heatsinks and my cpu.... click the link in my sig for the big typhoon and you can see my cpu lapped, but the pic of the BT is factory...though i have lapped it since the pic was taken

the process of lapping is to sand/grind down the surface so it is perfectly flat... which as you can emagine, will make contact with another flat surface(your cpu) better than if it were concave or not flat. also lapping is to smooth the surface out of any scratches and groves, which will trap very small pockets of air, and air is a terrible heat conductor. using 1200grit+ paper makes the surface almost a mirror finish, which helps the thermal compound work better (Arctic Silver 5 is most reccomended)... all in all i usually see about a 4-7c drop in load temps, and sometimes as much as 10-12c drop.... IMHO i feel lapping is well worth its time and small amount of cash...


to lapp a surface you need a SUPER flat surface. where can you find one? GLASS!!! glass, such as a window or mirror is perfect.... use this glass as the "table" or work surface, then place your sand paper on the glass and start working the cpu/heatsink on the sand paper in circular or figure 8 patterns to ensure even wear. then after you have evenly ground the metal down, move to the next finer grit and so on.... you typically want 400,600,800,1000 grit papers for lapping (1500+ is optional) also wet sanding typically works a little better and quicker....



PS: wow i think this is my longest reply ever!! lol sry guys, but its very descriptive....

hmmm how much as5 did you use? your supposed to use a very small drop of it on the cpu, like the size of a small pea or a BB... and you just put the drop in the middle of the cpu,dont spread it around, and install the heatsink allowing it to spread the AS5... also make sure the BT is tightly screwed on, its a BIG cooler so it needs to be on really tight....

Alcohol on paper towel works best.
