Thermaltake Volcano 12 problem.....

Hi there,

Yesterday I recieved from Dabs my shiny new Volcano 12 HSF. Fitted it within 15 mins and fired her up. through the night I tested it steadily and eventually ran 10 loops of 3dmark. My temps under load were 45 degrees with the fan on 2800 rpm which I thought was pretty good! compared to my coolermaster DCHP1 (or whatever it is) which under load were giving me temps of 55 degrees at 3500 rpm.

Oh, I should just mention that I put the thermal sensor on underneath the CPU so I could easily set it to auto-mode later on if i desire, but I wanted to primarily set it up on Manual control so I installed the 3.5" drive bay controller.
Anyway, seeing as I leave my computer on all night, I left it on last night and at 1:30am as I went to bed - all was ok after a great session playing Deus-Ex.....

Our lass woke us up this morning saying that my computer was making a lot of noise..... I was half-asleep so didn;t give two-****s. When I was awake I went into the room and yeah - it sounded like my fan was on 5500 rpm. So I switched the monitor on and checked my Soltek Hardware Monitor - it showed the CPU on a nice 37 degrees but yes, my fan WAS on its max of 5500 Rpm even though my manual 'knob' was turned down to 2000 rpm.....
Hmmmmm.
So, I swivelled the knob forward and backward to no avail - the fan was stuck on 5500 rpm! (and very loud!!!).

I shut comp down, undid the case and had a butchers. Yep, the connector was still on for the manual cntrol. I undid it, reseated it and connected it etc. booted her up - no difference, it was still stuck on!
So I tried again, and still no difference... BALLS!
So I set it up on Automatic and it was fine. it defaults to 4000 rpm though and adjusts accordingly uwards (not downwards) so its always loud-ish on auto....

ANY IDEAS WHY THIS HAS HAPPENED?

Suggestions welcome because I'd hate to return it after it was performing so well!

Can the thermal censor under the cpu be disconnected if so try disconnecting it.

well yeah, it can be but why would that affect my manual control? It isn't even plugged in when im on manual control.
Sorry not doubting your suggestion - it's just that id have to re-apply thermal paste etc to do that and if it didn't work then I'd have to do it AGAIN to get back to auto (which is the only way it works properly at the moment!).

Cheers

I can only say that with the thermal sensor disconnected and the variable fan speed switch connected there might be a problem with the switch or the wires connecting to the switch :confused:

Have you tried the other fan controller to check whether it is the fan controller that is faulty?
I assume that you had your little blue jumper appropriately used/removed?

TT has had a reputation for making flaky fans and realted components. As BUFF has recommended, try the PCI fan controller. Myself, haven't had any issues with my V12 since purchasing it last year.

k thx guys, i will try when i get home..... :)

have got exact same cooler and keeps be xp2100 at 35 all the time :) have had same prob - 3,5 drive controller thing packed up, dont know why etc. but use the pci one, works perfect, maybe worth emailin Tt about it, i would but am too lazy to find an address

lol! thx :)
I will contact TT if I can't get it working, cos I prefer the controller at the front if possible...

Also, You know how there are two connectors off the fan? The diode (auto) connector and the standard (manual) connector, right? Well, although I am using the manual one, I dont have the jumper on the non-active one... should I do that first?
Although I'm doubtful because It worked just fine without the jumper for most of the night....

hmmm
I'll let u know
