Scientists have thought that magmas that form new crust at fast-spreading ridges rise up from the depths, quickly crystallize, and then push away from the ridge to form new ocean floor.
To stop a computer from overheating never keep a cloth or something else on the CPU or monitor. Also use the save energy option from properties so as to switch off the monitor when not in use. This will always help in keeping the computer cool and not overheating it.
Since we now know that low voltage RAM has a measurable impact of system power draw, it stands to reason that low voltage RAM should also run at a lower temperature. The question now is if the lower voltage will also cause lower CPU or GPU temperatures, or if it will only affect the RAM sticks themselves.
