You need to file between both holes to create a larger hole? I was going to say because as is the peg moved to the inner positions will only go in at an angle, the pushpin won't go into the board vertically straight. Do you have a picture of your CNB-S1L as filed? I'd just be interested to see the result. Thanks again.

Hi Aln688, how's it going ?. I had to file between the holes first to get my round file in and then at the inner most hole by about a 1mm at each end to reduce the hole spacing ......

And fitted .......

Add small washers to prevent the spring going in the hole making the clamping forces uneven.

CNB-S1L = 53 degrees : SLF-1 = 44 degrees (on mid fan speed setting CHA FAN2)

some one know vmem read for this?

you might find the reading point searching all arround the condo's and more generally arrount the DIMM's. If I do find it I'll come back and tell

Hello there Rob2K, not bad, you? Thanks for the picture, I get the point now. I measured the distance between the holes on the southbridge, it's 53mm. With the S1L at its inner most points being 54.6mm, obviously a light filing on that heatsink will do the trick. I've looked around online and there really aren't any SB heatsinks that will fit this board, it's no surprise people are turning to this option. I have an HR-05 SLI/IFX in my computer parts box, I'm just reluctant to use it as it seems OTT. One item I do wonder about is the RPM on that SLF, does it sound loud? I have a slow speed 80x15mm 2000 RPM fan I could use on my HR-05 SLI/IFX, just toying with the different options, but your board with your SLF and modification looks great. Cheers.

Yes, good here too thanks. Just changed my Thermalright sinks to MST-81's - not an easy thing to do with the board in situ !.

The SLF fan is rated at 28dba at its max speed of 8000rpm, compared to the 6x120mm fans in the case and the 3x40mm fans on the memory mine is inaudible spinning at 4300RPM on the chassis Q control silent setting. You could always set it to between 50-100% speed using the duty setting on one of the 3 optional fan headers for more control. I would recommend this without hesitation or the CNB-S1L if not trying to max out your system - I have to run my S/B at 1.6v.

Another strap-performance update guys - minor but useful maybe:


Read and Latency performance at 500FSB/CL8/1:2 (CT Strong)


As posted before, at 475FSB, 200strap/tRD6 and 333strap/tRD7 give equal Read and Latency with CL8, but 400/tRD7 Read and Copy are lower / Latency higher.

Unlike 200 strap at certain CL/FSB, the 400 strap does not allow lower tRD than 333 strap.

200 strap still allows CL8/tRD6 at 500FSB/1:2

Unlike results at 475FSB, CL8/tRD6 at 500FSB gives higher Read than 333 strap/CL8/tRD7. 400strap/tRD7 still has lowest Read and Copy / highest Latency.

Allowing CL8/tRD6, the 200 strap is able to give Read performance more comparable with 475FSB/CL7/tRD6 on 266 or 333 straps (EDIT: for same CPU clock).

The 500FSB/200 strap advantage is not available with CL7, as 200strap/1:2/CL7/tRD5 is disallowed before 450FSB

Consistent with a load increase, 500fsb/CL8 using 200 strap/tRD6, appears to need higher min vNB for same Large FFT (in)stability, compared to 333strap/tRD7.



500x8 / 1000 / 1:2 / CL8 / CT Strong


tRD7 / 400 strap




tRD7 / 333 strap




tRD6 / 200 strap

Nice work there cheapseats, as always, very good.

Yes the MST-81's are great; solid, heavy and fit perfectly on this board, I have two installed around the CPU area.

Interesting about the fan, that's true you can use the Q-Fan feature on the board to control the speed. So does only OPT_FAN 1 to 3 fan headers let you control the fan duty speed? And is duty speed the same as percentage of total RPM for the fan? What does CHA_FAN 1 to 3 give you? Silent, Standard and Turbo settings?

I'm going to use two of these on my case, one rear, one front:

Farnell in the UK should stock them, or Maplin electronics in Leicester as I remember.

I'm going with two small 80x15mm Sanyo Denki's on each of my HR-05 heatsinks. I like your idea of the S1L with a fan on it, I just can't be bothered filing away to make it fit, plus I already have an HR-05 IFX/SLI in my parts box anyway. Both fans on the HR-05's are being plugged into OPT_FAN 1 & 2. The case fans are being plugged into CHA_FAN 1 & 2.

I should have all the parts in a few days, but when I get it all installed I'll post some pictures here. I'm going to need some nylon washers for the HR-05, I read a review where the reviewer said even tighening down the thumb screw the heatsink still swivelled, adding a couple of washers under the M3 thumb screw should fix that problem.

That's the other thing, Thermalright in the instructions recommends thermal compound on the chip and the heatsink base plate! I don't think so, I think I'll put compound on the heatsink baseplate only, because its smaller than the surface of my Northbridge chip.
