Adding a temperature sensor to PSU?

Hello masters!

I would like to add a temperature sensor to PSU, and I would like to read the temperature via PC (software).
Is that possible to do? (under an affordable way).


Thanks in advance
 
Well, you would be voiding the warranty on the PSU just to do this, not to mention it can be dangerous. So why not get a fanless one like we recommended in your other thread on the same(ish) subject...? Or a hybrid with a switch? But you will be paying through the nose for the hybrid.

Make it easy on yourself, get that fanless Seasonic I mentioned in the other thread. ;)
 
I still bear in mind your options and I consider them, but I have 2 problem with them.

*With fanless PSU Problem is that I keep the PC into an open bench case and the PSU can't have air (even if I put fans on cpu cooler and vga cooler).
*With semi-fanless PSU Problem is that I cant determinate with 100% accuracy when the fan starts itself.

So I thought to pick a normal PSU and drive the fan with an analogic rheobus myself. But I need to know the constant PSU temperature. (to avoid the danger)

*Another oprtion could be to pick a fanless PSU and match it with an external fan but I need to know PSU's temperature as well.
 
Fanless is still an option... they consider things like little/no airflow. Heat will naturally cause some flow on a case. my 1KW Seasonic is set to no fan on an open test bench.

Well, another suggestion that was mentioned in your other thread (these really need merged...) was to stick with Seasonic and get X560. I cant get that fan to spinup unless Im overclocking CPU and GPU with heavy loads on both. And even then, I cant hear it at all.
 
If you get a good PSU you will never heard the fan.
My Antec HCP-850w and Silverstone Strider 1000w have very quiet fans, I haven't heard either one of them speed up, and can't hear either one at all unless my ear is right next to the unit.

I would not attempt to control the PSU fan manually, a fan level that works great with no load may be fatally slow at high load.

Nor would I open the PSU up to add a sensor, it's a touchy and possibly dangerous operation. One of those things where if you have to ask whether it's possible, you really shouldn't try it.
 
You don't hear the fan but condenser microphones hear it.
Ok I don't go for the sensor and I send an email to seasonic asking for fanless psu on a test bench and asking for the semi-fanles load (when the fan starts).

I'll let 'u know news
 
If it is total silence you're after, by far your best bet is some long cables and putting the computer somewhere else.
 
Word. If he needs complete silence, Im not sure why a PSU with a fan is even a consideration. Seasonic fanless 400W FTW.
 
If it is total silence you're after, by far your best bet is some long cables and putting the computer somewhere else.

Bobnova, I think you're onto something there. Theoretically, if you had long enough keyboard and monitor cables... Hell, better yet, what if you modded wireless keyboard and mouse to transmit a high-power frequency? You could have you're box in another room, keyboard, mouse and montior in other room, all you would need is one cable between the monitor and motherboard! Lol.

:rofl:
 
Unfortunatly I can't get a machinne room for PC nor putting the PC into another place.

I don't need total silence all the time, only 10% of the time.

I probably will go for the fanless and to be sure I ask to seasonic [problem are the low watts 460 max (and I have bought a wat-calculator). And the air flow for PSU on bench test question]
For the semi fanless-the problem is to make sure that PC doesn't pass the 20% while playing the project and live recording (I doubt).

Calculating and let you know.
 
The Q9650 and 5850 combo will be around 300W with both CPU and GPU at full tilt. So a 400W PSU will be fine considering one rarely runs both CPU and GPU 100% at the same time. ;)
 
I still say the fanless Kingwin 500 will stand up to the load better than a 400 while keeping inside it's temp range. Heck, mount a fan to the outside of the fanless unit if need be, powered by your Rheobus and able to be turned off when need be. Warranty in tact and tailored to your needs.
Fanless units have their sinks connected to an external sink that's part of the shell, stick on a thermometer to track it's temp if you wish to see...then there's no alarm to interrupt your recording.

**BTW, you've said you can't move the PC out of the room, but can you move watercooling outside of the room? It's no big deal to stick a sink on the power supply as well as the CPU & GPU and let the water move the heat elsewhere that fan and pump noise is fine.
Just another thought. My water cooler is external, and it would be cake to add 30 more feet of tubing. You can even hang it on a wall..

Hello I have bougth the wattmeter and taking consumption. idle around 89Watt and full not more than 250 watt! (without monitor).
I sent an email to seasonic and they told me that the fanless in an open bench situation is ok.
Now the next step is to get a good SSD.
Thank you all for your help!
