Truepower 430 Temperature Adjustments?

[Junquenito]

Ok ... I've been searching various forums and sites for a while now and have found nothing to help.

I just purchased a Truepower 430. I love the fact that with the case fans plugged into the PSU "fan only" connectors I get ultra-quiet results, but it's raised my CPU temp's (predictably) by about 5C.

CPU Temps at full load--
Plugged into the "fan only" connectors: ~45C
Plugged into a normal connector: ~40C

Research shows that the Truepower's temperature sensors don't kick in the fans until the temp hits 40C. Well, fortunately (or unfortunately) my case temps never get over about 35C at full load.

Preferably, I'd simply like the PSU temp sensor to kick in at ~32-35C instead of 40C but have no idea how to make that happen. Alternatively, it would be nice to have the PSU kick in based upon CPU temps instead of ambient/case temps but again, I have no idea how to do this.


Everyone I've asked so far has simply told me to suck it up since there's no harm in the CPU running at even 45C or else to attach a fanbus for manual control. However, I'd like to know if anyone has already addressed this issue in the way I'm proposing.

Anyone have any tips?

Why don't you just plug the CPU fan into a regular header rather than the one with "fan" on it?

Sorry, I don't have an answer to your question but I would like to know as well.

Because it's quieter on the "fan" one?

Exactly -- I can plug the fans into a normal connector but I'm looking for the best of both worlds; fans ramped up and cooling fully when gaming / busy and fans quiet when not in use / websurfing.


I'd prefer to be able to use the thermosister in the PSU, but might end up having to use a fanbus instead ... just hoping someone can provide some direction =)

That is the way the PSU is designed and plugging just the CPU fan alone into a regular power plug will reduce your CPU temp. You won't get any better answer without having to totally mod the whole PSU. There is no temp adjustments on this PSU. It's just thermistor pressed against the PSU heatsink. I have this PSU and I already know that the FAN plugs has lower voltage than 12V. It won't ever turn faster than the one plug into a regular power plug.

First -- guess I needed to clarify it's the casefans, not the CPU fan plugged into the connector.

And I'm not opposed to modding the PSU if there's some way to get the thermosister to kick in when the case temps are at ~35C instead of the default 40C.



So far however it seems as if I'll just be stuck with the case fans into a regular plug (/fanbus) or else live with the higher case temps =)

Thanks for the input though.

Dou you mean plugging it to one of the cables that come out of the PS instead of the connector on the MB? Do they make adapters for this?

 

[Junquenito]

Burrens -- not sure what kind of connector is on your CPU fan but yes ... shouldn't be a problem at all to connect it to your PSU instead of your mobo if that's what you want to do ... just a 3pin to 4 pin adapter should do it.

However, you'll lose the ability to monitor the fan RPM (typically the yellow wire of the 3 coming of your average CPU fan).

I will probably pull apart my Antec TP 480 Sunday afternoon. I don't like the decreased exhaust flow because of the fan control. I'll let you know what I find inside it.

In that case you need a separate fan controller as I don't think you can mod it unless buying a more sensitive heat sensor to put in.

I have an issue with the 430 Truepower, I need to hookup the blue/black wire to monitor fan RPMs but don't have a place for it. Any ideas?

 

[syberscott]

If your motherboard doesn't have any monitoring slots left there isn'y much you can do.

Yeah, I may be out of luck, thanks
