Solve : Samsung NP-R580 laptop overheating?

1.	Solve : Samsung NP-R580 laptop overheating?
Answer» Hi, I have Samsung NP-R580 laptop. It comes with BA92-06128A motherboard and Core I5-430M 2.26MHz processor. From some point on it started overheating. These are the steps I have already taken to try to resolve the issue. I have cleaned inside (heat sink, cooler...), changed the thermal paste (as I dismantled and reassembled it), flushed BIOS from 06JB to 11JB version, made sure Easy Speedup Manager is set to Normal mode, no overclocking is applied from BIOS or wherever (I actually didn't EVEN find any overclocking related menus in BIOS). Open Hardware Monitor shows temperature as high as ~90C (194F), the record high has been 100C (212F). It takes around half an hour in idle mode to get to these temperatures. If doing simple things like browsing internet or music, video, even using Win explorer it overheats much faster. Please help.Sounds like the heatpipe as part of your heatsink may have sprung a leak and so its unable to draw the heat away. I'd look into buying a REPLACEMENT heatpipe/heatsink for it. You might have to search amazon or ebay for a used one that is specific to your model. I had a Fatal1ty Abit motherboard that had a CPU that was roasting and same issues you have. The heatpipe sprung a leak which was not detected and so the heatpipes were non functional. The Pentium D 3Ghz was running 80 to 90C. Tried new thermal compound and still roasting. Thought maybe the thermocouple was bad in the CPU, but touching the base of the heatsink with finger it was roasting hot, while top of heatsink was cool where fan was upright with heatpipes coiled at base and thru sandwiched aluminum up either side of fan. Swapped the original expensive heatsink with a cheap $15 heatsink with copper slug embedded in cast aluminum with new thermal paste and temps dropped to normal less than 60C when gaming. Research online pointed out to heat PIPE failure!I would agree, it's either heat pipe failure (time to buy a new cooler) or bad contact between the CPU and heatsink.Thanks guys. Hmm, what's inside that pipe? Is it a water or some special fluid or just alcohol? I'm asking as I didn't see any signs of a leak there. Also, if I can feel that heat coming out of the rear vents, does that not mean that the heat is actually conducted from the CPU all the way to the cooler and dispersed out of the vent? Regardshttp://en.wikipedia.org/wiki/Heat_pipe The vast majority of heat pipes for low temperature applications use some combination of ammonia (213–373 K), alcohol (methanol (283–403 K) or ethanol (273–403 K)) or water (303–473 K) as working fluid. Quote Also, if I can feel that heat coming out of the rear vents, does that not mean that the heat is actually conducted from the CPU all the way to the cooler and dispersed out of the vent? For some REASON your heatsink is not able to keep up with the heat being created by the processor and possibly the GPU which may be paired up with it as seen in some LAPTOPS where heatpipes are joined to draw heat away from both CPU and GPU to the hot air vent. And the only solution I can think of is swapping the heatsink with another. My socket 775 heatsink I could not find the crack or any signs of a leak with it, but it was clearly not functioning properly so the liquid must have escaped since it cant dry up inside the copper tube. All it takes is a hairline crack or an extremely tiny hole for the liquid to escape as soon as it turns to vapour, there would almost certainly be no sign of a leak as it's a very small amount of liquid.Thanks guys.It's the heat pipe, shouldn't be too expensive.
