Murphy has again found his way to the BOINCstats server. My decision to use a Prescott based Pentium4 now causes problems. The CPU is running very hot, and is clock-throttling its way through the scripts.

At the moment the standard Intel box-cooler is used. I’m searching for a better cooler that can handle this CPU and keep it cool(er). The problem is that most coolers are designed with noise level in mind, not cooling.

I need your help in this search. Let me know what you think is a great cooler. Watercooling and nitrogen are out of the question though!

Are some sites that I am checking out with a new invention of mine. Except I need a fan that can handle extreme cold....good luck in your search though.

Hey there,
I do not know if your Mobo can support a bolt on CPU cooler, but as far as an air cooling solution you may want to look at the Swiftech MCX 462 heatsink. I am currently using this cooler and to me it is superior to any cooler on the market. I an currently running an AMD XP3200 at stock settings, meaning not OCed, and at 100% usage my CPU is at 33C with a case temp of 16C. It is an 80mm cooler, but I changed the stock fan cause it was too loud, I installed a 120mm to 80mm adaptor, and it is quiet and extreemly efficient. I think it has to do with the sheer weight of the cooler a whooping 689 grams of copper and aluminum. If you are interested you can find the reviews at www.tomshardware.com they have a listing in there, under the CPU section summarizing a list of the best 42 CPU coolers that are available to the public. If you cant find it just search under "swiftech" Good luck in your search...

Howdy,

I was researching coolers a while back, and came across the upper line of Zalman coolers. (http://www2.newegg.com/Product/Product.asp?Item=N82E16835118115). The thing is a monster in size, but it will cool like nothing else.

Thermaltake Volcano is doing a very good job of cooling my overclocked CPU. All copper and 80mm or more in fan size is the way to go. I've got the fan on mine at half speed because if you turn it up full speed it moves so much air it sounds like a vacuum cleaner.

Even a cheap 'low grade' water cooler is better than air cooling.

I would seriously reccomend a water cooliung system. I built mine from scratch.

1 Eheim 1048 pump
Required amount of 1/2" vinyl tubing
1 Polar Flo water cooler [url=http://www.coolercases.co.uk/water_blocks_polarflo.htm' target='_blank]http://www.coolercases.co.uk/water_blocks_polarflo.htm[/url]
1 Suitable Radiator (I use a automotive transmission cooler with 2 120mm fans zip-tied to it)
(optional) reservoir (good idea to have one, mine is made out of a rubbermade tub)
Coolant (I'm using a 70 water 30 coolant mix)

All these of, course, can be bought in a package from thermaltake or something, and would work better than air. Mine is pretty shade tree also, you may want to try some things. If you want any information I have on water cooling, let me know! It is way easier than it sounds, and for the 3 years I've been doing it, I have never leaked anywhere.

I might also add I have my radiator hanging out of my window, and allows for some REALLY cool temp in the winter time here in Alaska.

I don't think the datacenter would like a watercooling system in their racks.

Well, I hate to say it, but I told ya the Prescott isn't the perfect Server CPU.

While I can't help with your choice of Cooler to keep this power-hungry monster happy, I just donated a bit to help you getting one

Hey Willy...If I Donated some cash to ya...How would I Donate PLN( Polish Monetary Unit) I dont make much over here...but I guess I could do away with some part for a good reason. :wink:
Just tell me how.

It's not possible to donate Polish money through paypal. I think if you donate € or $ it will be deducted from your account in PLN.

I just wanted to weigh in on this issue with a couple of simple thoughts. They may not apply to your situation but may help others when using the HOT running Prescott. 1) You said you were running the "stock Intel" cooler solution, if Intel can design a 125 million transistor CPU, surely they can figure out how to keep it within its thermal design limits. The real questionable part of their design is the use of a thermal pad. I have read many studies where this is potentially an awful conductor and its only benefit is to the novice installer who can't figure out how to add a paste thermal compound. Are you using a good paste (e.g. Arctic Silver) or the OEM heat pad? 2) The Prescott instruction sheets have a separate warning that the thermal solution relies on the case ambient be kept below 38C for their HS/fan to be effective. Obviously, the lower the internal case temp, the better cooling you will get out of any HS/fan. What is your ambient case temp? Do you have adequate case fans to vent the hot air out?

OK,so lets say I Donate...you still didnt answer my Question? How can I ? I think I would need your Account Number for that? And also Bank...etc? Also, what other method is possible? PayPal is out of the question since I moved to Poland...before it was ok, but now they have to restrict me. Polish people can not be trusted!!!!! Eventhough I'm American....LOL...Irony!!!!

I'm not familiar with transferring money to my bankaccount from another country. I'll have to check this out. I think I need at least the international bank number or whatever is called. I'll get back to this.

1: I'm using the good stuff.

2: This is the problem. Not so much the cooling of the case (I put in as much casefans as possible) but the ambient temperature where the server 'lives'. It is on top of 15 other servers in a closed 19" rack. The co-locater lowered the airco-temp with 2 degrees last friday, but that didn't help much. I've asked him to change the position of the server to below the middle of the rack so it can suck in cooler air. I'm waiting for results of that action before placing a bigger cooler.

The problem with air-coolers is that they can't lower the temp below the case-temp, so that should be fixed first.

You need to give your IBAN and BIC code.
If you don't know them, your bank will know. :wink:

About your problem with the Cpu, you can't "simply" change it for an other Cpu less hungry and hot ? you buy an other cpu and you sell this one ?
or i'm afraid that you will have always problems.

I need a very fast CPU to parse the XML files and to update the stats. It already takes a very long time at the moment.

Maybe I'll give Intel a call and try to get a P4EE LGA775 based on the gallatin core.

OK, I've looked around for some coolers, and I came down to the following selection:

[url=http://www7.alternate.nl/html/nodes_info/hplg04.html' target='_blank]GigaByte GH-PCU22-VG Heat Pipe[/url]

[url=http://www1.alternate.nl/html/nodes_info/hplt70.html' target='_blank]Thermaltake Big Typhoon[/url]

[url=http://www1.alternate.nl/html/nodes_info/hplz07.html' target='_blank]Zalman CNPS 7700-CU[/url]

GigaByte is not a pure cooler designer, so I might not be the better choice. Tests of the Thermaltake show this is a good cooler, and maybe I can outfit it with a faster spinning 120mm fan (the shipping fan rotates at a low speed).

The Zalman can't be outfitted with a better cooler.

I take it you have a 2 to 4 U rack. That could be part the problem - need to talk to someone who has a similar setup. Moving it where the surrounding heat is less than where you are located now, will certainly help. I have a 3.4 GHz in a big Antec case and I am experiencing no problems running 24 / 7 since 01-03-2005. I can however feel the heat coming out of the back fan - feels like a mini hair drier.

There are a total of 4 fans in the case. One in the PS, one on the CPU (That is an Intel. First row of numbers is C725704-002), one in the front of the case and one in the rear. Yes it is noisy, but I am hard of hearing so I really don't care. If you want the other numbers on the Intel fan let me know.

The problem with high ambient temps have been covered, but that is obviously part of the problem - need to get some cooler "air" into the machine.

Warm regards,

Gary

I have a Zalman CNPS 7700-AlCu here right now, and it really looks like there's no CPU on earth this Monster could not cool :shock:

Be aware, though, that this thing is huughe with a whopping 136mm diameter, so you'll have to look up the Motherboard compatibility list before making a purchase.

With its 120mm fan running upto 2000rpm, it should easily do the trick.
