i just wanted to have one just for show, but if its accurate then thats better. i want to put it between the rad and inlet of the cpu block. or maybe from outlet of cpu block to gfx, what you guys think, or is there a better one out there

it looks like there is two Cº ratings, does it take more then one temperature? it looks cool, but no idea on how accurate it is.. that thing is cool though...

hung · Jun 12, 2005

hmm. maybe it measures case?
dont no what that other one is for
yeah id like to have some kind of temp sensor in my loop cause probes are inaccurate.

honhon · Jun 12, 2005

personally i would assume one would be the water temp and the other would be ambient case temp?

hung · Jun 13, 2005

yeah, im sure thats what it is

Diggrr · Jun 13, 2005

Looking closely at the display, the top one is alarm temp--the high point you set at which the alarm sounds. The bottom one is the probe readout.

It doesn't mention if it's calibrated or not, but it is a Thermalsteal(take) so I'd bet not.
It is nice to have a second opinion over just feeling the tubing though...that's how I view my Aerogate. Truly accurate devices can cost more than the computer did.

i was just thinking that this morning as i looked at the front of my thermaltake sviking case, as i have the same type of sensor in the front bezel.

Depends on how accurate you want, you can get ~.5C for a few dollars....

How to get accurate temps:

Buy a t-splitter. Put it somewhere in your loop and hook up a tube to it. Buy a good old fashion mercury thermometer and stuff it in the tubing. Get some nice silicone caulk and seal that baby up. Tada! Accurate temps.

such a good idea...and so obvious LOL good one kayson, i just might do that

and what does calibrated mean diggrr?

citronym · Jun 13, 2005

calibrated simply means the accuracy of the device has been tested and unified with a standard.

a thermometor might say its 75º outside, but it could be off. testing the termometer to be sure it is accurate would be considered calibrating it

hung · Jun 13, 2005

lol and as diggrr said, it wasnt hehe

sad, it looks so unique lol, im gonna see if theres any around that ARE accurate

Diggrr · Jun 13, 2005

You can get an idea of how far it's off using a quality mercury thermometer and a cup of warm water. If the sensor isn't adjustable, then you'd at least know relatively how far off it was, and make mental adjstments from there.
And by quality I mean laboratory grade like those foot long yellow ones.

Take a look at some of BillA's testing devices he used in his articles on the front page. That's what I meant by truly accurate when I wrote it earlier. He invested some coin to help us all....
*edit* I looked up his Fluke 2190A Digital Thermometer. I found it for $450...used.My lanparty, corsair gig, and a64 dtr were $365.

It's funnyhow far off a temp device is allowed to be, yet even the lowly tape measure is inspected by the government in manufacturing, and by the ISO system when you use it for manufacturing.

I think pHeastus did an article on procooling about how to go about calibration.

Well I just picked one of these up, It should be here tomorrow I will let you know how well it works once I get to play with it.

Kamel · Jun 14, 2005

yea, that's the same thing as my thermaltake fan controller without the fan controller part. the temps are reasonably accurate.

he's right, the top part is the alarm temp and the bottom part the actual temp reading. the alarm temp is adjusted with a small pot-looking thing with a small screwdriver on the bottom right hand corner.

Daddyjaxx · Jun 14, 2005

I think you may be disappointed with it if you are using 1/2" tubing. I picked one up from CrazyPC. When it got here, I had quite a laugh. There may be separate adapters for 1/4, 3/8, or 1/2" tubing, but where the water passes through is 1/4". I would say you are going to restrict your flow pretty bad.

I sent mine back.

Gettygetty · Jun 14, 2005

from what it looks like I can take it apart from the T and maybe get a larger T to place it in.

hung · Jun 14, 2005

doode that would be sweet, keep us updated on if you do decide to widen the inlet of the T. but it is a hassle for you and others if they buy it and have a 3/8, 1/2 setup.

Gettygetty · Jun 17, 2005

Ok I got my stuff last night, First thing I did was open the Inline Temp sensor and took it apart.. Grab the keys and wallet and went to Home depot..

Found the fittings I wanted then started ripping bags open to make sure everythign fit right before I left the store..

EDIT: I used a 3/8" 'T' joint and used a 3/8" to 3/8" barb on both sides with a 3/8" to 1/8" converter to put the sensor In the top.

Total cost about $5 USD

Here is the outcome..

ahhh, very nice!
