Removed IHS on Opty 148 - No difference :(

[CRUSH-ER]

WTF?! The damn thing still get's up into and near 60C with a BT, AS5, and a 80 mm fan pointed at the base of the unit. This drops temps slightly more, but I'm still noticing nothing changed from before when I used both. I felt the base of the BT and it wasn't anywhere near hot. Are some Opty's misreporting temps? Has anyone ever put a temp probe on these things to see if they match up? I've felt 60C on a heatsink before using a stock cooler and there's NO WAY in HELL this is running at nearly 60C. Otherwise, I'm pleased. Love IHS less cpu' and knew I still had it in me. ;) . :cool: This is at 1.6V and around 3150 mhz using BT with great contact, AS5, fan aimed at base, and orange TT 1300 rpm 120 mm fan.

update your sig with your rig and maybe we can get to the bottom of it not reading right not all boards are opteron friendly for temp probes,,,

It could just be a misread.

I don't think you're getting good contact. Unmount and check the contact.

[CRUSH-ER]

I've been doing this a long time my friend. :) I reseated to no avail. The heatsink gets the stain of AS5 on it and it's as far down as I can twist the bolts. Contact seems to me 100% for me.

Do you test in a upright or flat position of your mobo...?
The issue I had with my naked 148 and the Zalman 9500 is that the weight of the HSF... even with supports... made it tip over just a bit... enough to make the temps go real high..

Flat, always has been, always will be. Sitting flat position with motherboard on metal pull out tray.

If you have any sort of compression springs you can use from a water block, give that a try. I used the stock mounting kit with the BT and it was *terrible*. Worse than my Zalman 7000A.

I reused the mounting screws and springs I had for my MCW6002 block and now I'm loading at 43C overclocked to 2.7 vs 53C stock.

You can also try putting a small coin (nickel or penny) underneath the clip that goes over the heatsink to give it a bit more mounting pressure.

Honestly guys -- I appreciate all the help and responses, but if I tighten it any more, I'm pretty sure it's going to crack into four equal sexy pieces. :)

I'm never a "know it all" and will re check it, but I'm 99.9% positive it's as far down contact wise as it can go.

Another thing I thought I'd mention is -- right before I bought the Opty I was using a A64 3000+ Venice with the spreader on and temps were dropped dramatically low under idle and load with my tricks I use and the big typoon with AS5. So I just want to dispell that I have it mounted wrong here.

Same BT on Venice? You might not have a flat base. I had to lap the piss out of a Tuniq Tower to make it right. I think a percentage of all HP coolers are bad that way. The plate that contacts CPU gets warped a little if they're not carefull when putting it together.

Worth a look.

All cpus mis-report temps and ALL temperature monitoring chips (ITE in the case of hte DFI nF4's) mis-report the temps. So dont be bothered by the fact that the reported temps are high.

Yep, same BT. Same cleanup job, same AS5 application, same mount.

I have looked at this and it'd be a valid thing to look for had my Venice not been cooled to extremely low temps. ;)
