Hi,

I was building my new computer. After latching down the CPU, I kept the heatsink in place. Before locking it down, I thought it would be better to change it's orientation for better cable management. I lifted the heat sink up, without realising that the thermal paste had already spread across the CPU. (Intel i3 3220, heat sink came with thermal paste pre-applied).
I immediately kept back the heat sink (within 20 seconds). Now I'm afraid there might be air bubbles, or maybe it won't work as efficiently. Should I reapply thermal paste? Or should I try booting up the system, and check CPU temperature in BIOS? If so, what would be an ideal working CPU temperature.
Please help. Sorry if there are already discussions on the same topic.

When you lift the sink, you're right, you can introduce air bubbles to the TIM. Its hard to say w/o firing it up and checking temps. If I were you I would just reapply and be done with it

Its not about how long the sink was out of contact with the CPU. When you lift it, being that the TIM is tacky, it pulls apart like silly putty and thats how the air gets in.

Thanks. I am thinking of buying Arctic Silver 5. Any suggestions whether it should be pea shaped or a vertical line? I have an i3 ivy bridge processor.
