Studio 1558 randomly slowing down. Temp is a bit high

Question

Well basically i have had a Studio 1558 for a month or 2 now. It has a HD4570 graphics 'card'.  The problem is whenever i play games on it, it will be fine for anywhere between 10 mins and a couple of hours then it will suddenly start lagging to the point of being unplayable. I have a widget that shows the cpu load, while playing the game normally only the first core is maxed out and the rest are pretty low (10-20%). When it starts lagging they all shoot up to 100%. A couple of days ago i decided to download CPUID to check the temperatures of the CPU and GPU. The CPU goes to about 70 degrees playing the game but the graphics card is up at about 100 degrees. I haven't had it lagging while having CPUID running so i'm not sure if that is the cause of it or not. Either way 100 degrees seems really high. Even at idol its sitting at 60-70 degrees. Are these temperatures normal for the Studio 1558? Anyway i followed the instructions on the dell user manual and took the laptop to bits to see if the cooling fins were blocked. The gpu is covered by some chunky aluminium fins and a heat pipe which heads towards the fan but does not thermally connect to anything, so there is no fan assisted cooling for the GPU.   I don't know much about cooling so this might be a daft question, but shouldn't the heat pipe be connected to something? So basically I want to know if the heating is the most likely cause of the lagging, and if 100 degrees is normal for a laptop GPU. Thanks in advance

Hi Kronu,

Do you perhaps have a 1558 user manual in electronic format (PDF). Would appreciate it if you could forward it to <ADMIN NOTE:Email id removed per privacy policy>- cannot find any on the internet. Much appreciated.
