If you did change the fan, be sure to not screw up anything, because with out the FHS you have no warranty!
I have that set up and have replaced it with first a lapped BT and a SS 121 then upped to a Ultra 120 with the SS121.
If you watch the For Sale section a lapped BT will likely pop up for a fair price... best inexpensive bet
But, if you do figure out how to safelly remove the stock fan, try adapting up to a 92mm.

Ok, you got me curious and the fan simply pops of by prying the outer tabs!
That leaves you with no easy means to retain a fan unless it's the exact same diameter and thickness to "replace" the original Nidec Beta V TA275DC!

BTW, that Nidec rates a max flow @ 41CFM so if you can find a higher volume unit you know what you have.

The Ultra 120 is very good but not all that cheep (939), it's improved version or the Ultra 120 Extreem don't usually have the 939 retainer and ships with AM2 and Intel brackets
The U 120 is easy to install and the Silverstone 121 varable speed fan works well with it!
The fan clips are a bit tricky on the Ultra 120 are a bit tricky in that, some fans, like the SS 121 have a boss between the mount holes and have to be cut away for the retainter clips to work!
Note the Coolmaster attached fan, the inner part of the housing has the fan holes open unlike the SS 121.

Do you know of on good hs/fan comb that you don't have to bolt up, i'd rather just use the clips.
post #7 of 11
I personally use the Thermalright SI-120 which does not require bolting through the board. However you do need to remove the motherboard to replace the AMD stock bracket with a custom bracket supplied by Thermalright. This custom bracket looks just like the old Intel Socket 478 bracket.

The problem with the stock bracket is that it is only rated for a few hundred grams load. A typical aftermarket HSF will exceed this specification quite easily and therefore a more secure method is needed (hence bespoke brackets or bolted through the motherboard)

hope that helps

If you won't be overclocking your Opteron 165 higher than where it is presently, then something like a Zalman CNPS9500 will be fine, provided that your case airflow is adequate.

A Thermalright SI-120 or even its slightly older sister, the famous XP-120, will be even better. With a Thermalright, you have the advantage (or disadvantage, depending on your perspective) of choosing your own 120mm fan. I've got the XP-120, and it's relatively easy to install.

On the other hand, there's no reason to be reluctant to use a bolt-on HSF. I prefer these, actually, as I find it's easier to use a screwdriver than it is to move my hands in a confined space.

Just a few thoughts to ponder, though.

Then I recommend going for a more robust cooling system.

The XP-120 is a classic, and is relatively easy to mount. You just need to take off the stock HS retention bracket from your motherboard, replace it with the included custom retention bracket, then clip the XP-120 on. Oh, but you do need to get your own fan.

I've also got great results with the ever-popular Big Typhoon. This is a bolt-on cooler, though. However, it's very easy to mount. I didn't even have to remove the board from the case.

For a cheaper solution, but one which will require more work, you can take the testimony of many on this forum and go with an Arctic Cooling Freezer 64 Pro, lap it and graft a more powerful 92mm fan onto it, then mount it on your Opteron. I've used this HSF (it was the very first aftermarket HSF I ever tried), and it does a decent job for dual-cores, but tends to struggle with the higher voltage requirements of more severe overclocks in my experience. Of course, I never modified mine (I used it on a customer's rig instead, which ran stock), so I can't tell you how well the mods could have worked.

Hope this info helps you!
