Rosewill LGA 775 heatsink $19 shipped

[sjwaste]

I have a passive setup on my Socket A HTPC that this will go into, so if a 120mm Yate Loon fits, I'll definitely be moving one of the case fans to the heatsink. Keep us posted, and thank you!

Okay guys, I just got home from a friend's house, and the package was here! Talk about prompt shipping. I ordered Saturday night and they actually had a tracking number for me on SUNDAY. Monday it's in transit. Tuesday it's at my doorstep. I'll have some pictures up in a few to show you the build quality. From my initial impressions, I'm kind of impressed and a little anxious to see what she can do.

Here's what I can tell you off the bat:
The fins on the heatsink are way more stiff and rigid than the fins on an AC Freezer 7 Pro. Coming from me, that means a lot because I'm a huge advocate of the Freezer 7 Pro. I custom mounted a F7P with a 120mm fan combo for intake and exhaust and basically launched the ACF7P to levels of cooling and silence that compete with Ultra 120's and Tuniq Towers. That means a lot when you're talking about $5 of scrap metal, a $20 heatsink and two $4 fans.

The bracket holding the copper contact on uses stock socket 775 push pins. I would've liked more, but really that's all the Hyper TX2 and ACF7P offer as well, so I can't really complain. One could purchase bolts if they wished along with a backplate. The weight of this heatsink doesn't really demand that caliber of bracing.

The fan does have 4 PWM for anyone concerned with noise levels and customization. The ACF7P sits a bit taller, but the Rosewill cooler is wider. I really like the "solid" feeling of the heatsink fins. The ACF7P and Hyper TX2 fins seemed rather bendy to me, and while it's not something that bothers me because the stability of those coolers and performance speak volumes, having something rigid and stiff in your rig gives you a feeling of comfort. The fan itself appears to use 80mm mounting brackets, much like the Akasa heatsink it's compared to. The bracket itself though spans wider and taller so I'm hoping I won't have to customize too much to fit a 120mm onto it. I'm going to grab an old 1x120mm radiator and use the shroud from it for measurements and piecing together.

Hopefully my issues with Directron don't turn out to lead to a cancelled order, so you guys will have a test this Friday showing the cooler versus a F7P and stock cooling and hopefully even 120mm fan cooling on two processors: A 2160 stock and OC'ed and a 6750 OC'ed. I would test the 6750 stock but my friend is way too happy with my 3.0ghz OC of it.

My sister just got home, real time pictures coming up!

ordered on 1/31, just received it today. egg has been alright with shipping, though buy.com is most definitely faster for me on most occassions.

I was quite puzzled which direction the fans operate - blow or suck. at first I was mistaken about the picture in the included manual and thought the fan sucks air out. one guy in the egg review commented how you shouldnt orient it so the fan on the heatsink and case fans blow in the same direction. to clarify what he said, the fan sucks in air to blow it across the heatsink.

cant comment on the cooling capability of the HSF as I havnt gotten a chance to do much experimenting/tweaking the speed and vcore yet. one thing I noticed was how loud the thing was, totally opposite from my expectations. there is a chance that I might have connected the 4pin connector wrong, but the manual reads " this connector is keyed so the power lead can only be installed one way", so I assume that is unlikely. maybe the PWM is faulty, who knows.

wondering if I should install MBM or Everest to tame the fan a bit...


edit: looks like its my biostar mobo not wanting to cooperate with the PWM on the rosewill. just remembered that I had a spare zalman fan controller lying around, hope that does the trick

Orient it so it pushes air through the fins.

Perhaps you have to adjust the BIOS settings? There's often a temperature threshold, max temp, slope and fan starting speed.

I look forward to some reviews - especially from NamelessMC. Not talking about his sister either. Since he's used the ACF7P and is a self-proclaimed advocate of it, and because that's the exact cooler that came to mind when I first saw this one.

Ok, I have to ask...what is "bump"?

 

[NamelessMC]

Bump means they're bumping a thread up for recent viewing and for people to ask for responses.

Here are some pictures:

Top View
-You can see how rigid the fins are. It has a very solid feel to it. I don't have an ACF7P on me, but this Friday when I test, I'll be sure to drop some comparisons
On top of 120mm Fan
On top of 120mm Fan 2
-It looks like a bracket might need to be made to 4-screw mount a 120mm fan, but not that big of a bracket. For reference, my TX2 adapter was about 2 inches taller than the TX2 heatsink so the adapter was rather awkward shaped
Stock Thermal Paste
-It's an actual paste, and not a thermal adhesive pad. Chances are it won't be as good as AS5, but I'm going to test it with the stock thermal paste just so people that don't have AS5 get an idea of how it ranks. The ACF7P has an excellent thermal adhesive on it, so for 1:1 comparison, I'll leave the stock thermal paste on so people know how the two heatsinks directly compare.
The board I'm throwing it at
My Gigabyte P35-DS3R. Match made in heaven? Well you'll just have to see, won't you?

Nice braided stuff on the fan wires. Thanks for the pics.

The actual HS quality looks better than my TX2.

You'll be doing the legwork for me. I picked up the same HSF, and have AS5 on hand.

Just wanted to throw in my two cents on this. I got this cooler yesterday along with an E2200 (I know, waste of $ over 2160, but I've always gone a little TOO cheap on systems I've wanted to OC, so I paid for the extra multiplier) and P35-DS3L.

I didn't test against the stock cooler because I'm really lazy, but for what its worth, I fired it up at 273x11 (3.00 Ghz) and ran CPUBurn under Ubuntu for about 15 mins. Kept it under 46C with both cores loaded.

As an aside, XP did NOT like the change from a 939 system to a C2D, so its hosed and won't boot pending a reinstall, but the Ubuntu 7.10 install I had handled it just fine. I'd strongly recommend making a 10 gig partition and installing just in case you can't get into Windows for whatever reason. I was aware XP would probably take a dump, but I chanced it b/c of the backup OS, and was able to back up all of my files.

 

[Burrich]

Yeah, some precautions need to be taken when swapping over. I bet there are guides out there related to this. I've done it before and remember needing to delete a number of items under the Device Manager related to the bridges prior to swapping.

Repair always works good too.......:thumbsup:

Yeah, I've done it before with good but never perfect results, I always ended up reinstalling later on. So I figured I'd just try it with zero precautions taken, since I decided I was going to have to reinstall anyway. XP benefits from a reinstall every couple of years anyway.

I tried to run the repair just to see if it'd work, but it bombed and the install wasn't even recognized by setup when I rebooted. It's a good excuse to reformat and clear the clutter, or just stick with Linux.

Got mine a few days ago. Temps @ stock with E4500 OCed to 3.0Ghz w/ 1.328 volts where 30 at idle and up to 59 degrees at load. With Rosewill cooler w/stock TIM, temps are down to 22-24 at idle and 41 at load. For < $20, I'm happy.

Tried going a little higher on my OC, but ORTHOS failed at 3.2Ghz w/ 1.37 (1.4125 in bios) volts. Temps went up to 25 idle and 48 load (3Ghz with 1.37 V).

 

[Univac]

While this heatsink looks similar to the AC7, it doesn't seem to have the trouble mounting to an IP35-e.

(I don't have an AC7,but have read that some have trouble mounting it to the IP35-e..)

The rosewill clipped on no problem with mine.

Bump for results as well.

This is a heat pipe cooler of very similar design to the AC7 and will post almost identical cooling numbers. There is also a review of the Akasa AK-965 posted already, which is almost a dead ringer of the Rosewill HS. http://www.frostytech.com/arti...iew.cfm?articleID=2137

Plenty of information to make a decision regarding cooling capability.

Great deal for $17 in my opinion.

Yeah my bump was for the 120mm mod mentioned earlier in the thread...I already have the cooler and find the build quality remarkable for what it is. It exudes quality...more so than my Hyper TX2, or my old Sunbeam 92mm "Whisper" model.

 

[twistedlogic]

Bumb again,

Just thinking too, how does the actual bottom of the heatsink look with the TIM removed? Looking at both NamelessMC's and Frostytech's pics, they both show with thermal material. All I know from Frostytech is "The copper has a sanded finish which gives it a surface roughness of ~63 microinches."

Just wondering if for one, the bottom mounting can be removed(looks so by just removing that screw), and two, if it would be worth removing and lapping this cooler? Is ~63 microinches bad?

 

[straubs]

Twised, I think you mean bump.

I have this cooler, but haven't installed it yet. Are the rest of you using the included thermal material or scraping it off and going with Arctic Silver 5?

 

[bmwme]

I was already to pull the trigger on this. Added it to my cart, pasted in the code...then realized it expired the 4th I don't want to pay $6 shipping for a $16 part.


Guess I'll wait for the next deal to come along.

 

[twistedlogic]

straubs, I think you mean Twisted

I used the stock TIM on mine. Now I'm thinking about pulling it back off, lapping both the heat sink and CPU's heat spreader. Then reinstalling with some Shin-Etsu thermal grease.

I just hate to go through the install again, originally thought I broke one of the white locking tabs because they were not lined up right before shoving them down. I finally removed the MB to complete the install so I could see what I was doing.
