Silver Arrow performance with 2500k

Update: reseated heatsink, temps seem only a degree or two lower at most and that could be just because the machine was off for about 20 minutes.

So I seated it right, yeah. Maybe used a bit too much first time as there was some left over on the outside of the sink in a small clump all the way around. This time I used the smallest blob possible, basically the least amount that the tiny syringe would allow out.

Also while I had the sink cleaned I placed it on a table and yeah, it did wobble slightly. Should I lap it? And how do I go about doing that?

Thanks.

Edit: Biggest change is that now all cores are a lot closer in temps. Only 3c max difference between them that i have observed. Load temps are now high 40s to low 50s. yay!

Excellent - sounds like you did have too much gunk between the CPU and HS.

Those results/temps are great - it appears your temp anomoly across the cores was due to poor contact.

No its not worth it - your temps are great and the slight curve will get flattened out (to a degree) when it's secured to the bracket or using the pressure vault.

Experiment - perhaps even drop 100MHz - my vCore goes up dramatically (relatively) when i push past 4.5Ghz.

I wanted a compromise between a moderate clock and quiet/cool running.

so true, mine 4.4ghz @ 1.3v but i can get 4.5ghz stable at 1.37v
0.07V increase for 100mhz speed increase not worth it so i stick with 4.4ghz.

Quick question I forgot to ask: How's the paste that comes with the SA? Cure time?

Just wondering. I have a tube of ICD7 but... after wiping that off my last HS and seeing what it did to the surface of the CPU, never again. It left the markings intact thankfully, but it did abrade some of the surface.

It comes with Chill Factor 3 - which is quality gunk.

There may be a slight cure time - but i haven't noticed any difference in temps.

And damn, Core 0 had about a 7c difference compared to 1 & 2. Will have to resit for sure I think. Dammit.

Going to try re-seat heatsink all over again won't be any difference. I had try my silver arrow re-seated 8 times and core 0 still the same 7-9C difference to core 2. I think it natural.

Core 0 and 3 are the lowest temperatures. 1 and 2 are the highest.

Correct same here

Not for me. Reseating it fixed it. All cores report within 3c or so within each other.

How did you manage it ? Did you use CF III ? Did you put a rice blob in the center of the cpu ?

I hate that silver arrow fan clips, really hate it! (cos the bottom clip touched the ram - not a good idea!)

Yeah, I used the paste that came with it. When removing my first go, I noticed I had used too much. So I just cleaned it all up with alcohol, buffing it with tissue to make sure it was all good, and then did a TINY (as little as I could get out of the syringe at one time, which I was thinking was still a fair bit

)

Placed heatsink back on, tightened up (my god getting that retention plate back in with a 6950 to the left is a PITA. Then I just tightened the pressure knob until I had to use more strength than I'd have liked, so stopped then.

That seemed to have done the job of spreading it evenly and the pressure pushed the slight concave down more, enabling better contact.

That's all I did really. And yeah, those fan clips annoy the hell out of me when trying to get those fans on.

Temps are currently 33, 32, 34, 31

Ah, I probably never use the pressure vault bracket, I took it off. Because I thought it could damaged the CPU chip in the middle. ?

Only if you use too much pressure. Too much = when the knob wont turn 'easily'. That thing is there to be used. Thermalright won't design something that can bugger your CPU if you even touch it.

An 1336 socket has a pressure capacity of 60lbs. If you turn it full way, you're screwed. So just tighten it until it's snug, job done.

Edit: It doesn't damage the CPU itself in the middle, what it would do is push the CPU down into it's mount, meaning less contact and potentially ruining your day as you'd need a new MB.
