my old s939 dfi lanparty box finally died on me and ive been running the stock hsf on this i5-2500k until i decided upon a cooling solution I liked. That old machine had a ThermalTake Big Typhoon HSF on it which kept that Opteron 146 s939 cold @ 2.8 ghz.

Rather than buying a brand new hsf for 50-100 usd I was thinking maybe it would be worthwhile to recycle this TT Big Typhoon by somehow getting it to fit onto this i5-2500k LGA-1155.

Has anyone attempted to do something like this? Were the results worth the trouble? What kind of cooling performance should I expect to see with a HSF that kept a single core cpu ~25C @ 2.8 ghz on a quadcore i5-2500k?

as a side note, what do you all do with your old Heatsinks that don't fit newer machines?

Should I attempt to get this thing to fit my i5 or should I just shell out 100 bux on a new hsf?

What mounting kits are available that will permit me to get this thing to fit onto an 1155/56?

That big typhoon will do great on a 2500k. I used one to cool a 980x at 4ghz, SB's got nothing on that! It was aimed at P4 and P4 D stuff, 89watt, 115w, and 130w chips.

Mounting may be tricky, but doable.

Yeah, you will have to get inventive on the mounting because the Big Typhoon never was updated with a newer mounting system. But it should do pretty good. Not as good as a more modern heatsink but still it should be able to handle a SB up to 4.4-4.5 or so I believe.

That was one of the few Thermaltake heatsinks that was actually worth a damn. Especially if you replace the stock fan with something like a Panaflo L1BX.

looks like you're 100% correct here. The typhoon is too heavy for me to jerry rig a mount I think. The xigmatek crossbow 1155/56 mounts might work, however there are 2 tiny problems.

1) The crossbow wants the side clamps screwed to the heatsink base. There are no screw holes on this Big Typhoon but that doesn't mean I cant create 2 holes. However a smooth bore like that wont allow threaded screws to bite, but then there's always epoxy or bolts.

2) The Big Typhoon's base is rectangular and the Xigmatech could only mount to the non-heatpipe sides which might stick too far out to allow the top side clamps to be the right distance away from the holes in the Motherboard.


TT Big Typhoon base dimensions are 2 inches wide and 2.5 inches long
or 5.08x6.35 centimeters. The 1155/56 hole spacing is a square 3 inches. It would have to be mounted to the short ends that stick out the furthest. In this scenario it only leaves 0.5 inches of room between the holes in the board and the hole in the bracket. If I did my math correctly (my trig sux so i could be wrong, but it looks right) then I need a full inch of clearance which makes the base too large for the xigmatech brackets.

I cant remove the extra 1/4 inch on each side (total 0.5 inches) extension piece because it clamps the base of the heatpipes to the copper base.

Long story short, looks like I'm buying a new HSF unless I can get real creative in the next 8 hours unless someone smarter can come up with something. Im out of ideas and the other clamps I looked at wont work by a mile.

If you have a backplate already you can get a plastic cutting board and cut out roughly the shape of the normal TTBT bracket, then drill holes spaced for 1155, and buy some of the correctly sized threaded rod and nuts from a hardware store to bolt it down.

Much cheaper than something of equal cooling capacity, but also more labor intensive.

[muddocktor]

Yeah, that is an idea that Bob has. But it will take time and patience and a little bit of hand-working skill to do that. Of course, since you asked about modding the mount in the first place tells me that you aren't afraid of doing a little modding and have some skills already. You can buy an 1155 backplate and modify your present or make your own top "H" beam for clamping.

If you don't want to go through that hassle and want to replace it, I would recommend looking at the Thermalright MUX-120, which comes with all mounting equipment for LGA1155/1156. That will keep your 2500k plenty cool for overclocking.

Looks like i've got myself a weekend project. I'm pretty sure i can cut a custom H bracket or 2 out of either aluminum or steel, probably go with aluminum because it doesnt rust. Might put some extra holes in it to lighten it up if its more than strong enough

I think i can get away with 3 bars, one across the middle then the 2 on either end pulled on top and pulled toward the board to create a secure fit. I don't see a reason off the top of my head to fasten the 3 bars to each other to make a single piece. We'll see once I get into it what works and what doesn't, heh. I'll take photos and post if I remember to charge the camera.

One problem is going to be that these 1155 mobos have a metal backplate for the cpu clamp on the back of the board already. Ill have to design a different plate for the backside that works around the other backplate so that it sits flush against the board, otherwise its going to warp over time and inevitably loosen the fit of the heatsink to the cpu.

[Bobnova]

I would fasten them together.
The two end boards will tend to slide off the center one as you tighten the bolts down, don't want that.
