HSF suggestions for an incredibly hot dorm room?

edited December 2003 in Hardware
My problem is that my dorm room gets incredibly hot. It snowed here yesterday and I still had the window fan going. When it was 30 degrees outside my RA's room next to me was 91 degrees. So, needless to say it gets quite warm. It's been getting better as of late but it's too hot for my stock Intel HSF. As of right now it's 45.50 C according to Winbond Hardware Doctor. Yesterday when I played BF1942 it hit 61C :eek2:. I have Artic Silver 3 on the CPU. I already tried the ZALMAN CNPS7000A-ALCU and the temperature difference was 1-2 degrees and I quickly got rid of it.

I've been reading reviews upon reviews and the SP-94 seems to be what I need for my situation but I don't want to spend $50 for the HSF and then about $11 for the 92mm Panaflo I was looking at. The other thing about the SP-94 is the fact that it says it's better when sitting horizontally, there is no where in my room that I can have this case lay flat.

All of the reviews are in controlled areas, so has anyone actually used one or currently have one? Also any other suggestions would be appreciated. Thanks in advance-DaK

    Slk- (whatever the one is for a p4 ) and a 92mm sunon

    I forgot to mention, I'd like it to be as quite as possible :). Picky, I know. Watercooling is out of the question at this point in time. I don't even know what phase cooling is..soo..

    ...of heating system does your dorm have?

    PS: Your room might cool down a little if you change your avatar... :D

    Phase Change cooling is what goes on in your refridgerator. If wc is out of the question, phase change probably is too... it's $700-$1000+

    Anyhow, you have basically one option- thermalright SP-94, and an Enermax Adjustable 92mm fan.

    lol :crazy:

    The building I live in is 40 years old and I'm on the 11th floor. I have an old school heating unit by the window. There is no way to change the temperature, there's only one knob that makes the air coming in slightly cooler. My RA had to go all the way up to the VP of the Univ for them to turn the damn thing down. I'd take pictures of this stuff but my digi cam is at home.

    What kind of temperatures would you guess I would see? All the reviews get ridiculously low temps, but they aren't living in the equivalent of the Amazon either.

    [realworldresults]I just installed the sp94 in my system last weekend and my cpu temps went up, but that was coming from a 7000rpm fan to a 92mm 28db fan that moves ~49cfm. With 2 instances of f@h running, mine is sitting at 52° in my appartment when I have a fire going(it gets up to about 28°), without it's usually about 48°. That's the SP94, AS ceramique and a quite fan. The cpu is a p4 2.6 oc'd to 3.0. It was a bitch to install, and probably took me about 30 minutes to get installed(plus the 2 hours I spent rewiring and recableing)[/realworldresults]

    What were your temps with the stock fan? Thanks for the response.

    No clue, I never used the stock heat sink. I had this startech one.

    Is it forced air (i.e. just a vent that blows hot air)? Electric? Radiator?

    Yes, it forces hot air...really hot air.

    dak... calculate the thermal resistance of the heatsink, and you should be able to figure out your temperatures.

    Thermal resistance = (CPU temp - fan intake air temp)/heat output of CPU in watts

    I know my temps, that sounds mucho complicated btw :p. I'm just going to assume that this Winbond hardware doctor is correct.

    I'd like to play battlefield now, I'm assuming 61C wouldn't be a good thing? More importantly, is it damaging?

    Any chance of blocking off the vent? If you're handy with tools you might try removing the vent and look inside for a manual damper. (I'm an old A/C guy, among other things).

    Also, you might try to get chummy with the building maintenance crew. (Bribe 'em with a CD of bible music - building engineers usually like THAT...). If there is some sort of air balance system they could tell you how it worked.

    Being on the 11th floor, you probably don't need much heat at all (I'm sure you already know that...). I've had high-rise buildings where we had to run supplemental heat on the lower floors, while air-conditioning the upper floors, even when it was 20F outside.

    that was my same gut reaction GMTA!

    It is blocked off actually. Doesn't help a whole lot. Albeit, just with a thick blanket. The maintenance crew has no control over the heating, it is decided by the higher ups of the university (supposedly). I took the cover off of it and there is only knob, this knob makes the air hot or hotter, that's it. Some other guys have another knob but mine doesn't.

    Dak, you misunderstood... you want to know how much the SP-94 will drop your temps, right?

    Find a review of the SP-94 where they test it with (preferably) a known heat load, e.g. a wirewound heatsinkable power resistor, or a CPU @ 100% load.

    Use their data to calculate the thermal resistance of the SP-94; then, multiply that by the heat output of your CPU in watts, and you'll get the rise above ambient. Add that to the ambient temperature, and you'll have roughly the temperature you'd get.

    Ah ok, sounds good. I'll look into over the weekend, thanks.

    I'll do it for you if I can find that program that calculates a CPU's heat output... anyone know what I'm talking about? It's not radiate (which has never worked for me)... there's another program. I can't remember what it is, tho.

    Here's one of the reviews I read.

    Another
    This one has a lot of good links at the bottom.

    Maintenance crews have control over everything :D (trust me on this - I was a Chief Engineer).

    Could you rig a shroud to divert the heat out of the window? (When you get your camera back send in a picture, maybe I'll have a more specific idea).

    If nothing else, monitor the room temps for a week or so, then write a self-righteous letter to the school newspaper decrying the energy being wasted. Point out the irony in your having to wait for Spring to cool off. I promise you, there is a way to solve the problem. We just have to find it. :thumbsup:

    Ha sounds good man. Apparently the heating for this building is controlled from elsewhere on campus. Not sure on the details. I also don't plan on bringing my digi cam here, I don't want it to suddenly dissapear. The heat has an oval type outlet, there's no good way to get it out my window. When I have my door open and the window fan cranked it's comfortable. PC temps drop too of course. Thanks for the response, I'll try to think of something.

    At deafult 2.4 and 1.525 volts, that cpu Dak uses puts out 77.32 watts.

    At 3 gigs and let say 1.6 volts, 106 watts. Not that bad actually.

    However, a Barton 3000+ at default voltage of 1.65, puts only out 74.30 watts to cool down. ;D

    SLK-900 series, YS-Tech 3-pin high volumne fan, from svc. OR a Panalfo high volume on same HS,IF your bios will let you NOT detect CPU fan and you run MBM5 in alrm for temps-- which is what I ma doing until the Ys-Techs arrive. Barton is at typically 7-10C over ambient under heavy load and slightly OC'd with the Panaflo A12H fan running. I am getting the YS-Techs mostly as they are almost as quiet as the Panaflo is and gen about as much air flow and HAVE 3-PIN with sense to keep BIOS happier and let BIOS intervene if I am not home to hear alarming and shut down box.

    Ok, so I grabbed the data from Gruntville's SP-94 review; I came up with an average *C/W of 0.2; I'll assume that your 2.4C does 3GHz @ 1.575v, for a heat dissipation of 88.2w; with a Panaflo H1A 92mm fan, your temperatures should be ~51*C in a case where the intake air is the same temperature as the room, and the room is at 33*C/91*F.

    Well that's dissapointing :mad:. Thanks much for working it out, you just saved me quite a bit of hassle. Yesterday when there was a nice breeze coming through it was at 42.50, 55c when I played BF.
