We've just had the hottest April on record here in the UK (Scotland and Ireland still got the rain and cold) and my CPU and GPU temps went up quite a bit. I'd moved the PC around so maybe the airflow was not as efficient as before in my Antec 300. I had a late spring clean yesterday and opened up the PC for a clean. The last time I did this I had removed the fan from the CPU to get rid of the dust but it appears the fan was only 90% back in place. The dust has collected big time in the grills because of this. I also removed the Vapor-X graphcs card and took off the front fan cover to reveal more dust in the grills. A careful screwdriver removal and vacuum cleared all the dust and now the PC is cooler once more. The CPU has dropped 4-5 degrees and the graphics card is a full 10 degrees cooler under full load. The PC is now cooler and under less stress so will last longer as a result. Anyone else sufferring from the mini heatwave?
