Hi, Using either RealTemp or Hardware Monitor on Win 8 the core temps on my 3570k fluctuate up to 6 degrees a second. Is this normal, Is it actually physically possible to have such temperature variations ? Is it likely to be the software running on Win 8 or maybe the motherboard sensors ? Motherboard is P8Z77-i Deluxe with 0704 bios and a Gelid Tranquillo cooler. The cpu is not overclocked btw. Thanks.
