I have a zalman 9500 which has been utter crap in my experience. I have a 6400 @ 3.28GHz 1.425volts (cant get stable with less) running at 60Cidle and 75C full load.
Ambient must be around 20C or less, I'm in London...

Anyway, so I bought the tuniq tower a long time ago but every time I install it the computer wont turn on!
I thought maybe the problem would lie with my PSU. It's generic but has been fine with my existing set up.

I just cannot think what the problem could be when I install the TTower.

Any suggestions before my CPU melts?

check around when you install it you probly got somthing grounding out maybe try to setup out side your case and see if it powers up. I own the zalman 9500 and my idle temp is 40c and load is 58c on a pentd overclocked to 4400mhz you sure you your putting your paste on right ?

I put a thin rice sized amount on it.

Yeah my temps are crazy, the fan blows air onto the side of my case :-s. So I have to remove that side panel of my box so it blows the air out... or else my temps are 65-68C idle with the case completely on.

thats insane my temps dont hit that high even when i push my cpu to 4800mhz on the zalman 9500. For me spreading the as5 around the cpu with a flat object works better then the rice way. You cant mount the fan so it blows air out the back ?

Wow... that is hot.


Several good suggestions have already been made, but I am still baffled by the TT not only not doing its job, but performing so poorly.


Did you ensure that TT was mounted fully and evenly?

As already mentioned, it might be worth the effort to remove all the hardware from the case and running it on anti-static surfaces (just to be safe). Doing so will do two things for you: 1) you will see if it is a grounding issue, and 2) you will be able to get a feel for the cooling properties without the case constraints.

...besides, the TT is ginormous and I have read of members that have had issues mounting it. Mounting it outside the case will give you plenty of room to work... ...and cuss.

Question: Is that shorting problem specific to the Tuniq? Or just to any heatsink with a backplate? Or to specific motherboards when mounting backplates?

Did you have the cpu fan plugged in?


You must have screwed the backplate on funky...take it off and try it again. This time, tighten your screws up a little at a time, going in a cross-ways fashion...not clockwise. Dont be scared of tightening the factory hardware too much...just use your fingers. The screws are made to bottom-out at a certain point..most likely, your fingers will not be strong enough to get them that tight.

*Try putting a razor on your IHS to see how convex or concave it is...you might need a lapp job.

This sounds like the most logical, try putting a small amout of electrical tape on the side of the backplate that contacts the board and see if that helps.

My first impression was that he has something grounded, too.

Make sure you don't have any pins bent out of place. The 775 socket has the ability to have pins move around a bit and if they get bent, they will not contact the CPU properly.

The DS3 will not boot with a Tuniq Tower 9 times out of 10. Remove the Tuniq. Place a thin sheet of foam or electrical tape on the back of the motherboard behind the socket. Re-install the Tuniq. The DS3 grounds out and will not boot due to it's electrical layout.

Good to know! I didn't use anything between backplate and the motherboard on both my ASUS P5W DH Deluxe or my ASUS P5N32-E SLI. Guess I've been getting lucky!

True dat, I had the same problem on my board and fixed it with some bogstandard sellotape.

its specific to the giagabyte GA-965P series. i had this problem http://www.overclock.net/intel-cpus/...ghlight=wonglf . i solved it by putting 2 layers of insulating tape on hte back of the motherboard behind the processor and then one on hte backplate itself. i didnt take any pics but i might reseat it in hte next day or 2 so i will then.

it had me scratching my head for about 10 hours, but i got it in hte end.

I have no issues with my P5B-E either. It seems like the DS3 (most likely the S3 as well) is the only one so far.

May I ask how you did so?

Current situation: My temps are 50C idle at STOCK SETTINGS using the Zalman 9500... I'm gonna buy some of the tape described in this thread now and install the TT.

So, if someone could explain where to put the tape and will any tape do??

My hero too.

Success, I put tape on the back of the mobo and now it works fine. Currently:
3.2GHz 46C idle, 57C load.
