XP-120 vs XP-90 result

[yamawho]

Both systems built on P4C800E deluxe with 3.0C @ 3.4 Ghz.

Running 3DMark03 this was the highest temp recorded in asus probe:

XP-120 with a very tame startech 120mm fan 37 deg C.

XP-90 with a Enermax 90mm fan set at 2300 RPM 39 deg C.

I'm sure that if I had a high volume fan on the XP-120 it would be 1 deg or so less.

Keep in mind that alot of air flow does not translate into much lower temps.
I remember testing a Tornado case fan which has 3 times the airflow of a std case fan and the CPU temps only went down 1 deg. I could hear it upstairs it was so loud ... not worth it.

I would suggest getting a variable speed fan and turn it down alittle until the noise level is reduced. On the XP-90 the max speed of the fan is 2800 RPM, however at 2300 it makes half the racket.

As a final note both systems have three 80mm case fans (2 in rear) and I use OCZ powerstream 420 psu's.

Very good information yamawho, I definitely subscribe to your philosophy that more isn't necessarily better:thumb: The same holds true in cases a few well placed fans are much better better than many poorly placed ones:wave:

I know I am ressurrecting older threads :hide: (but it's not all that old honest :look: )

One quick Q or maybe something for a debate? With the xp120 and xp90 how were the pipes oriented? I picked up an xp120 and xp90 and the instructions do not say which orientation the pipes should be and they can be installed in 2 different directions. On a vertical mobo the bend in the heat pipes can be pointing down (below the level of the proc) or up towards the top of the case (higher than the level of the proc).

In looking at the design of both heat sinks I think there is an obvious improvement that Thermalright can implement. Currently the end of the heat pipes are at the edges of the fins and fairly close together. It doesn't make sense to me why the heat pipes are located at the edges and not in the middle.

Why not spread the heat pipes out equally across the width of the fins and a little more towards the centre so that they equallty distributed among the fins? The bonus with this approach is that the pipes would be in more direct path of the air flow from the fan which in turn should produce far better cooling results.

Now I am looking to see if there is anyway I can muck about with thier set-up without breaking the seal of the heat pipes - doubt it can happen.

BTW anyone running an xp120 or xp90 notice if these are hot - barely touchable suggesting the pipes are at >140F or 55C? I was discussing this with someone who was having troubles. Most were saying the proc is going. I suggested before he resign himself to this fact that there were some others things he could try and validate if it was his proc or possibly the heat sink was toast.

hahahahahahaha, sounds like the High Output Delta Fans I used to use.

[Snafu]

BTW I should have raised the question if running air cooling at what point is it really worth trying to get your proc cooler and cooler at the sacrifice of noise? If it runs ~52C (assuming correct readout) is there any point in trying to get it cooler if you cannot push the FSB up?

You might be happier with a higher proc temp (within spec) and lower noise from the case.

I guess one question is if the temps are within spec would running it at a cooler temp mean longer life. Conversely does running it at a temp within spec mean that the proc will have a shorter life?

While you're at it what's the meaning of life? 42?

On the P4C800E deluxe the only way to install it is the the pipes facing the north bridge cooler. One of the pipes actually fits in one of the ridges in the heatsink.

I resently installed a Zalman 7700 CU on another P4C800E deluxe and it fits much better.
Although I can't give you a comparision because this system has a 3.2E oced to 3.8 Ghz.
The temps BTW are 49 deg C max running Prime95. This HSF is fits more mobos than the XP120.
I didn't install the reostat on the Zalman so it runs at max speed about 1950 rpm with the 120mm fan.

Thanks. I gather with the P4C800 board there is intereference if it is fitted the other way?

I was "dry-fitting" the xp120 and xp90 on a IC7-max3 board - only the xp90 would fit. The xp120 intereferes with the mosfet shroud.

I noticed that the bracket allows you to fit these hest sinks either way - providing there is no interference and wondered if one way was better than the other.

Maybe this is something to test out if I can get either to fit the board is other directions.

Funny you shoudl mention the Zalman. I have a 7000AlCu I was going to try out as well. At the end of it all I will have extra sink sto play with - hmmm, maybe play around with trying to cool g-card

Cheers mate

BTW are you freezing your tooshie in Montreal? Its cold as... over here

[yamawho]

If you turn it the other way the capacitors are in the way.

It's been cold lately ...

I had read originally that the xp120 fit with the P4C800 board was okay but some bending was necessary. This was on the Thermalright site a while back and concerned some boards.

It could be that the bending required would be too much. I think it is time I started to paly around with the cooler and board and see what configs will work. I wonder if you can change the orientation of the bracket too?

Man, I have got to stop making up work for me to do :bonk:

Thanks bud. Don't freeze your you-know-whats ;)

The orientation cannot be changed. The socket is indexed 90 degs compared with most mobo's like the P4P800 for example. The XP120 does not fit on the P4P800 BTW ...

[Snafu]

Thanks bud :thumb: . I wondered why the fins were not pointing towards the ram like I had seen on other set-ups.

Hey, how hot are your pipes on the xp120? Someone was saying thier proc was 62C and pipes were barely touchable (= >140F or 55C). Could mean the proc is dying but I would not think the pipes would get nearly that hot - heck my stock heat sink does not feel warm even at its base. I suspected his xp120 coudl be shot but he continued on the path that his proc was dying. He was probably using it as an excuse to upgrade or rma :lol:

Cheers

Never had a reason to check ...

If you look at post #83 and 85 you can see pics of my setup with the xp-120.

Thanks :wave:

Very nice set-up you have there :thumbs:

I concur. . . . :rock:

[yamawho]

Thanks guys ... I started custom painting my cases awhile ago.

[Snafu]

I know this is off topic but what kinda paint did you use? The vinyl paint they use for car interiors or the stuff for patio furniture (I like thier red - nice and glossy)?

Now to keep it on topic - the pipes do look pretty close to a bunch of stuff on the board. Do you have rev.2 version of the board?

Yes it's rev 2 and yes very close. In fact one pipe rests on the heatsink for the north bridge in the groove.

The paint used on the system in those pics is Tremclad (dark grey hammertone) which I got at Cdn tire. It takes a long time to dry so after painting just leave it alone for about a week.

As for the temperature of the XP-120 I was running one until I got a Danger Den setup :rock: . I have the MSI Neo2 and had to bend a cap ever so slightly to make mine fit. I had touched the pipes while it was running and never really had it burn more of warm I would say. I also had to mount mine with the pipes down. Otherwise I couldn't use the ram slots close to the cpu even then it was a pain getting ram in or out while the sink was on.

[Snafu]

Leave it alone for about a week :yikes:

Hey harleyboy thanks for the temps of the pipes :wave: . A good point of reference.
