Thermal sensors

[camaro]

I was thinking about getting a thermal sensor since my asus one doesn't stick no more and accuracy of it was always in doubt.
I found this http://www.coolerguys.com/CPUCOOL/thermal.htm
I'm looking at the $16.95 one. I was thinking about sticking the output of it on the front of the case and attaching the sensor to the core. Does anyone know if I can semiperminently attach that one or is it made for just touch and read mode?

Cool, I'm getting it. What's a heatsink compound and where can I get it?

Roy's idea with the thermal epoxy will work fine..

However I prefer to use "superglue" as it's thinner which should allow good thermal convection and it's brittle so that you can snap it off when needed.

I use that method to adhere an Indoor-Outdoor type thermometer bulb to my CPU/HeatSink and get temperature figures concurrent with average ones on systems with "internal" temp pick-ups.

In my case, I also used some old plastic tubing as a shield from ambient case temperatures and air movement.

I found some clear tubing the correct size for the O.D. of the sensor, I slotted one side to allow attachment to the CPU/HS and stuffed foam in both ends to seal it..

One time I accidentially unplugged the CPU Fan lead.

A bit later I got some ODD BSOD's.

After a couple of re-boots and things were NO better I scoped out the inside of the case..

To my HORROR the little Radio Shack thermometer lying in the bottom of the case read -> 130.2F <-

YIKES !!!

A quick hook up of the leads cooled it down and all is still well http://www.sysopt.com/forum/smile.gif

127F is the alarm point on my other K6-2 475 (IBM).

The thing looks good to me...

Ive used one for quite awhile, added it to my Swiftech462 with some clear silicone, placed the thermistor between the pins and applied pressure while it set, doubleside taped the readout to the m/b since its visable, its pretty accurate compared to Sandra or m/b mon...

Rooted around, found an older pic:

Nice work on those rounded cables. They look like single ones, with no connection in the middle. Or is it just not visible? I was wanting to buy some, but I don't need the double ones and its just more mess in there. Can I get single ones somewhere?

So it's ok to just glue that thing on top of my cpu so its touching the core from the side? That epoxy is pretty permanent I read, and you're supposed to dilute it with thermal paste so its not so sticky. I just need a drop of something to keep it in place. I guess super glue will work.

DO NOT attach it to your cpu's core---a true reading may be read from the faceside of the heatsink as close to the core as possible, the thermistor has a fat insulator on it so I didnt trust that way (it would sorta have to be "smashed" possibly impeding contact???) ---I mounted it on the base of the h/s opposite side of the core, the heat transfer gives me an easily read close idea of my core temp---between 3 monitors it varys 1c so I trust it...

[camaro]

So stick it on the heatsink part that faces down and close, but not touching the core? I've seen pics on sharky or toms forget which one where the heatsink was off and the sensor was touching the side of the core. That made be believe that was the correct way. Now since its not sticking its just in free air in between chip and heatsink. Still the temps are close to what it was when it was sticking.

Heatsink compound (A.K.A. "Thermal Goop") can be found at Radio Shack.

I got the dual HD Rack/ Thermal Probes.. I just used a regualr piece of masking tape and touched the probe to the side of the core.. does a better job than Via Hardware monitor..

Looks Good!

The "3 second sampling cycle" implies it's meant to be left in place.

You could glue it in with a tiny dab of thermal epoxy, or the regular kind, as long as the sensing "tip" is in contact with the surface to be measured. I'd add a little heatsink compound at that location too.
