Nice roundup of high performance Heatsink/fan units there.

Some of them are very new. Back up to HardOCP's main page and look for some of the older HSF roundups for specs on some of the more common parts on the market. I know I can get a good Thermoengine with 7k fan here at my local place that would do the trick. See if you can find somebody that will install it for you too... with proper heat compound of course.

Haha, I thought I was the only one who's ever seen Hardocp here.

(BTW: Read the disclaimer in tiny print at the very bottom of their home page...)

Ok got the new DUO462 from Thermaltake, installed it and still got temp problems, so I put on my wrist strap and touch the fins of the chrome orb and they are reasonablely cool. The fan is turning at about 6k RPM, so I checked the BIOS temps against the via hardware monitor and they also say the cpu is pretty dang warm, felt around as close as I could to the cpu itself but couldn't make any kind of contact with it, wouldn't it stand to reason that if the cpu was really 156 deg F that the fins on the bottom of the heat sink should be warm at least

Either you have a defective thermal sensor, or you installed the heatsink/fan improperly.

You have to check always before installing that the core and the mating surface actually touch (on some heatsinks there are small plastic feet which you have to remove before installing them on AMD cpu's)

Secondly you have to use a good quality thermal paste, apply a very THIN layer of it evenly on the core and then carefully install the heatsink.

Did you mount it yourself? Are you sure the heatsink is sitting PERFECTLY flat on the CPU? Did you clean it first? Did you use a good quality thermal compound?

If they CPU is not making proper contact with the heatsink it would cause problems such as you are describing.

Did I read..CHrome Orb? They rot. I think www.coolerguys.com has many great fans. I bought a wincak38 all copper HS with big ol loud fast fan and it does well.

Batdog,

The Chrome orb is not a bad Sink if your not overclocking. It is not as good as some of the other out there, but certinaly does not rot. I think Tyro made an error in the instalation of the Heat sink. I hope it does not prove to be a costly one. I think, but i'm not sure, the Orb's come with the rubber feet on the bottom for use with a Pent III or IV processors. The Athlon Socket A chips have the rubber feet on the chips so they are not needed on the Cooler. If the Sink is installed with the feet still on, there will be a gap between the Sink and the chip. This is normaly fatel for the chip

I hop he didn't try to loadtest the machine yet!!

have a FOP38 on my tbird 1.2ghz. Works great, if a little loud.

It took me a while to clean off the sticky heat compound pad. I installed it with a dab of artic silver.

I'm running at around 33-34C, and 36-38C with the case closed (running aces). I also have 1 fan in front sucking air in, and a 7200rpm fan at back pulling air out.

Have worked in Electronics 30 years <G> pretty sure I have the HSF installed correctly, knew I was in trouble when I opened the box and saw the DUO462 ABC up front and personal <G> it just doesn't have enough mass to handle the heat, same prob with the old heat sink but it does better, so gonna have to look around for a heat sink that will not foul with componets on the KT7 Raid Motherboard and stll comes in under or at AMD's recommended weight restrictions for the 462 socket, any KT7 users out there who have solved this problem and still meet the 462 socket weight restrictions?

bloom25 · « **Reply #25 on:** July 03, 2001, 06:22:00 PM »

Take a look at the Thermalright SK6.

(Don't know about the weight though...)

vatiAH · « **Reply #26 on:** July 03, 2001, 06:45:00 PM »

Tyro,

The wieght restrictions apply to shipping. AMD does not reccomend shiping a computer with that heavy a Sink on it do to the extra forces that wieght adds when the Box gets moved around. The wieght is a NON- ISSUE if your going to mount it and just set it under the desk

Thermoengine and SK6 both fit the Abit Kt7 range of motherboards.
Had em both and no bending or mods needed of anything for them to fit.
Close call with the SK6 tho fitted it in a hurry fired up comp, on a whim thought lets check CPU temp in Bios before loading windows, the temp was at 80c and climbing fast !
Never killed the supply to the PSU as fast in my life.

214th, is it a design flaw, or did you just not get it on properly? I'm planning on ordering one of those and an AXIA pretty soon.

Also, what fan did you put on it?

214thCavalier · « **Reply #29 on:** July 08, 2001, 11:49:00 AM »

Bloom the bad fitting was my fault.
Not design flaw at all, i was in such a hurry to fit it as AH was calling

Lol you know the heat sinks have a step on them that corresponds with the socket edge, well basically in my hurry i did not get the step in the heatsink centred correctly over the sockets edge and of course was very lucky not to fry the cpu.
I have win98 set up with with 2 different hardware configs so it stops at a menu and asks which i wanna use, first boot attempt it froze at the menu which got me suspicous which is why i checked the temps in Bios next boot attempt.
Fans tried with the default SK6 ystech first temps were same as my Thermoengine with delta but quieter.
Fitted Delta to SK6 load temps dropped 3-4 degrees C.
One good thing that came from it my 1 Gig Axia Y overclocks higher and stabler now after being nearly fried

Totally stable at 1.4 Gig now not bothered to push it higher yet.
One other thing to bear in mind with Tbirds higher than 1.33 gig a lot of motherboards are freezing a couple of seconds after finishing loading into windows.
This is caused by windows ACPI power management, specifically the HLT instructions to cool down the cpu, as soon as it starts to cool down windows locks.
Cure is to install windows with ACPI disabled in the bios or with an install command line option "setup /p i".
Of course you can also disable ACPI in the bios of a current windows install but be prepared to have to reinstall all your hardware drivers upon windows startup.
Disabling ACPI will make your comp run at full load or close temps all the time mine currently 50c reported.
But for a huge overclock from 1 gig to 1.4 i can live with it

Actually keep meaning to try a software cooler like softice or similar to see if they cause the freezes as well or just windows ACPI implementation.
