I noticed my temps have been a little higher lately. Not abnormal but higher. I remember they used to be like 20-30 degrees idle when I first got it, and now i'm idling at about 40-50 degrees, and under load i'm at about 60-70 degrees which again I know is normal but idle temps seem a bit high.
My pump is set to "extreme" and is making a whining noise? It sounds like coil whine, and is only noticeable really when set to extreme.
I also noticed that one tube (hose) vibrates quite noticeably when you touch it, whereas the other tube is very close to still/no vibration.
