I got my water cooling setup going not to long ago and I wondering about my temps, to see where improving can be done. My system is all home built and consists of a cpu block, a reservour with a submerged pump, and a very large radiator though its not the most efficient design... just copper pipe sandwiched between aluminum heatsinks. I know my temps are higher than most WC systems but my rad is running passively and is tucked in a corner. Anyway heres my temps: CPU is 48°C -> says my mobo, The nf7's read on the highside AFAIK Water temp is 40°C -> this is accurate Ambient temp around rad is 26°C -> this is also accurate. I'm thinking on building another rad and move the whole system into the case so I'm just wondering if I should address other areas as well.
What does your loop consist of. As you mentioned, the NF7-S does read high, the latest Abit BIOS seems to settle it down a bit.
Would you still be using the same pump? I'm wondering how much heat it's introducing into the water as it's submerged...
My loop consists of: CPU -> Pump & Reservoir -> Rad -> CPU. I guess it would have been helpful to mention that those temps are with the CPU loaded. Also I'm using tictac's D26 Mantaray XT-1T bios so I have no idea if he recalibrated the temp sensor or not. In the new setup I'm thinking on getting an in-line pump for the reasons you mention, jetsetjimbo. I haven't looked too hard yet but so far I'm leaning towards the Danner Supreme Magdrive 3 or 3.5 which ever it is. It's their smallest one that has 1/2" in and out.
why are you worried about your temps? Is your system unstable or do you looking to OC further? If its stable and your not planning on doing anything that will produce extra heat then you dont have to worry about the temps.
