TRUE vs Scythe Ninja

post #1 of 15
Thread Starter 
Right, so I had a Scythe Ninja on my old build, and I decided to use it when I swapped in my new Q6600 and mobo last weekend. With the CPU at stock, it was idling at 37/38 degrees, which seems a little too high. After having read all the positive publicity I decided to get a TRUE, which I received and installed yesterday, but I was sorely disappointed when I looked at my temps; almost no change whatsoever.

I should explain at this point that I have an Akasa Ecplise 62 case which is pretty good for ventilation, so I very much doubt it's poor airflow. My TRUE had a very well-machined underside, so it's in no need of lapping either. Anyone else experienced a less-than satisfactory result with their TRUE?

You get the TRUE or the thermaltake ultra 120 (non-extreme?)

(edit) Ah, n/m, say your sig.(edit)

Also, what fans are on the TRUE?

I've heard that lapping to a mirror shine has an effect regardless of "well machined," but you're right the TRUE is supposed to kill the scythe.

Yeah exactly, I was expecting a bit of a difference, even if it was only a few degrees. I've got a Scythe 120mm fan on the TRUE at the moment, it's the only spare fan I had at the time of assembling it all, but I'm planning on changing it for something else. Recommend any decent fans that have good airflow but are quiet at the same time? My two case fans are Akasa Ambers and they've been pretty good so far on noise, probably not the highest airflow though.

After having read reviews on the TRUE and seeing some truly horrible photos (TRUEs with big gashes in the contact plate etc) I was expecting to have to lap it, but it was pretty damn good as standard. Not quite mirror shine, but not far off. When I installed it I had to remove it once and reinstall, and when I looked the AS was showing pretty good contact too. I'm at a bit of a loss really

Can anyone recommend me a decent fan that'll give me a good compromise between CFM and noise levels?

even though with that fan your temp couldn't be the same, TRUE pwn Ninja period.
something is wrong.... perform razor blade test?

do you mean use a straight edge to determine if the contact plate is flat or convex?

those temps are pretty high. Are you sure you have enough pressure on the chip? I get those temps at 3.4ghz and I don't have the greatest cooler.
I read somewhere that about 70psi was ideal for heat transfer. I will try to dig up a link

Edit: here is the link
IT says that when you get close to 70psi the thermal resistance is much lower

If only I had a way of determining how much pressure was being placed on the heatsink

I read about placing a penny between crossbars and the base of the heatsink to increase the pressure, I may give it a go when I remount the HS.

I had to mount the HS at 90 degrees to the usual angle though, rather than mounting the heatsink perpendicular to the rear case fan I had to mount it perpendicular to the PSU (due to space restrictions). This means that the fan is blowing air through the heatsink up to the PSU; this wouldn't affect temps that much would it? The PSU fan is still exhausting the air from the heatsink out the case.

It shouldnt affect temps that much if your psu is pulling the air out of the case. I would recommend you go to best buy and pick up a rocketfish for anywhere from $55-90 depending is the sale is on. I think a new case could help you out a lot

I'm in the UK, and I don't really want to buy a new case, the one I have is supposed to be pretty decent cooling-wise (one of the reasons I bought it), and it used to have no problems with my overclocked Athlon I was running before I swapped in my Q6600.

*edit* what do you guys think of this fan? http://quietpc.com/gb-en-gbp/product...ns/nf-s12-1200
