Here's what I use currently:

For water temps (wb in and out) and air temps (rad in and out) I am using a Digitec 5810 thermometer and YSI 700 series linear thermistors. Not perfect, but two of the water probes read exactly the same (to 0.01C) over the range of water used.

For CPU temps I use a Maxim 6655EV System from dallas semiconductor. I bought it because the homemade readers are limited to the resolution of MBM (1C) while the maxim software is 0.125C (over || port). It took some fiddling to get it working acceptably.

For wb testing, I am primarily relying upon the delta T across the waterblock at this time as I still don't know how relevant the diode temperature of the CPU is. I am pretty confident a superior block will put more heat into the water though.

Flow rates are basically "the master variable" for wb testing, and I use a GPI paddlewheel type digital flowmeter. It has a substantial pressure drop, and I compensate with a beefy pump (Little Giant 3E-12NYS)

All this was ebay/surplus/leftovers from BillA. Not sure about the YSI 70x thermistors, but there are some cheap digitecs on ebay now.

Ok, not exactly what I am looking for. I will try to make this more clear. I am not looking for temp reading accuaracy for testing water blocks on a professional level. I am talking about a senario where someone has a setup that just want to get a decent CPU temp. Something that does not require flow meters and all that. Something the average water cooling user can use to take temps without all you guys saying it is not right. Otherwise there is absolutly no point in anyone telling their temps at all because you all will say they are not measured right which in some cases is clearly obvious they are off but in some it isn't so clear that they are right or wrong even if they seem off base. Also I would much rather have a digital display show the temps as opposed to mbm on the computer. Is that possible?

re: 1-2C error. We have gone over this before; start propagating the error forward in the calculations and you will see why better numbers are needed (Uncertainty proportional to sq root of the sum of squares).

Yes, I know this, but to the average user who just has one setup it is really imaterial and these are the people I am trying to refer to as I am one of them. Maybe this miscommunication is what been causing all the arguments lately. Because if you guys want to make this a strictly professional forum then you will not get many posters.

2) Maybe we could get Bill to put some of his tests with Swiftech bps of differing thickness and material? I think he has changed his testing methods since the testing was done, but he might be convinced

Well I am not sure if that is what I ment either. I would like to see it explained in plain idiot english what happens when heat or cold is applied to Copper and AL. Like a good example of why copper spreads the heat betterthan AL.

3) Also cheaper just to buy a faster CPU (at least with AMDs). Stock CPUs run 60C no prob; why not just stick with whatever free MHz you can get with the retail heatsink and thermal pad?

Well this was a real constructive answer that has zero to do with the question.

I can see why things get so miscommunicated around here and ending up in disaster.
