My Sony Vaio VPCEB34En laptop's CPU and GPU share the same heat sink and fan. I removed for cleaning purpose. After I cleaned my fan, I mounted them back. At first, the laptop didn't power up and the fans are not spinning. Then I checked to see whether my CPU is seated well and it wasn't. I fixed that well and now using the laptop. But the GPU and System temps from Speedfan were showing high temps. Here are the conditions:

Before dis-assembling CPU-GPU-Fan assembly (SpeedFan temps with one-tab browsing):
CPU 46-48 C
GPU 56-58 C
System 56-58 C
CPU Fan 4260 RPM (this was the highest recorded RPM even when playing games)

After dis-assembling and reassembling CPU-GPU-Fan assembly (SpeedFan temps with one-tab browsing):
CPU 46-48 C
GPU 65-68 C (at most went to 73 C)
System 65-68 C (at most went to 73 C)
CPU Fan 4500 RPM

So where did I made the mistake that made GPU alone go hotter but not the CPU?

The thing that comes to mind is thermal paste. Did you reapply it or just leave it?
Edit: +1 for HW Monitor. Shouldn't matter that much but just to be safe...
