Hello guys, I`ve been trying to solve my overheating problem for quite a long time, but had no luck, so I will try to describe it to you and hopefully, someone can come up with some solution. I`ve also read numerous topics about heating problems, but that didn`t help me at all. My specs are Core i7 2,3Ghz with nVidia 650GT, 8GB RAM, 500GB HDD, OSX Mountain Lion 10.8.4. SMC reset is not helpful in any case, did OS reinstallations many times with no noticeable effect. MBP is 1 year old, I have cleaned it up from dust and also did the thermal plaste reapply (Arctic Cooling MX-4). I use iStat pro on Dashboard and iStat menu for temperature monitoring in OSX and Mac fan Control along with Real Temp in Windows 7 (Bootcamp). Room temperature is pretty cold and I use two table fans directed to the MBP to help cool the alu case and also, MBP is elevated about 1,5cm in the back and 0,5cm in the front for better heat dissipation. Now for the temps and issue itself: In OSX, it usually idles at about 45C average with default 2000rpm fans, quite no problem with that. All cores are +-3C around 45C. which seem quite fine. When really idling for few minutes, sometimes it goes lower even to 37-40C. I do not really game in OSX, but when I do (GRID 2, DIRT 3, and other more demanding games on low to mid settings) I set the fan speeds always to max 6200RPM. But even if I do, temps usually wobbles around 95C and I experience thermal throttling sooner or later. Temps do not stay at 95-100C but they oscillate, probably due to thermal throttling. Temps are generally better in OSX as it should be, but I made another test with Prime95 under both systems. OSX: I use torture test (in-place large FFTs: maximum heat and power consumption as stated), all four cores go 100% load, which are supposed to. I set fans to 6200rpm everytime I test this. Starting from idle temperatures and MBP case pretty cold, temps are like this: After 3 minutes, C1 is 88C, C2 96, C3 99, C4 95 After 5 minutes, C1 is 91C, C2 99C, C3 101C, C4 98C Then it goes celsius by celsius up and up, about 20sec/1C more. Core 1 is usually able to stay under 95C, while C2 and C3 are running up the most, even to 104-105C, C4 is a bit lower, about 101-102C. Same torture test under Windows 7 shows similar pattern, except idle temps are about 55C and load temps go up little faster, while gaming under W7 (Battlefield 3 on lowest setting except resolution, which I use native) is experiencing throttling and Realtemp shows reaching 104-105C eventually on C2 and C3. Of course, I`m worried about my MBP and I do not want it to suffer any heat damage, so I stopped playing for now and hoping for some solution you guys may help me with. Please notice, that MBP is not under warranty and there is NO apple store in Czech Republic, where I live. I did few thermal paste replacements before this one and I believe I made it correctly. Temperatures before the paste replacement we`re slightly worse than I have now. Thanks for reading and your help.
