Madshrimps Forum Madness - the belgian phase changers :)

so there is a problem with the abitth7-II.

thanx to JC for doing all the fieldwork towards chip-con so they could get it solved...

"Dear Prometeia User.

It has come to our attention that a couple of customers have had some difficulties in assembling the unit properly the first time. It has however shown by thorough investigation, that these incidents except with one specific Mainboard (the ABIT TH7 II), mainly emerge from lack of understanding the two basic and most important features of the Prometeia Cooling System.

· The first being, the issue of proper thermal contact with the Core of the CPU. The fact that the Cooling head does not fully cover the heat transfer plate of the P4 on some MB’s is not an issue of concern - the actual Core of the CPU is much smaller. However, insufficient pressure towards the heat transfer plate is very much a concern, and the manual describes in the mounting instructions for the P4, how to adjust this pressure to achieve full and effective contact by adding spacer rings.

· Due to a difference in the threaded brass Stands on the mounting Clips, with respect to our original specifications, it is recommended to place 4 spacer rings on the screws holding the Cooling head in place. Units shipped out after the 4th of June have those already. Units shipped prior to that date does not have them, but spacers should be included with the kit.

· The other issue of concern is that of Condensation. The Prometeia is delivered with a very efficient Seal String, that totally prevents any vapour diffusion into the hermetic Cell, as long as it properly closes all gaps into the Cell, also gaps under components caught under the mounting bracket. Other important parameters of the Seal String are that it does not cure (harden), it is removable without leaving any sticky or greasy trace, it settles very quickly under appropriate pressure. It is not recommended to use any other sealing method or material, as that will result in formation of Condensation.

· On the issue of the ABIT TH7 II MB mentioned earlier, the matter is slightly more complex. Due to a couple of components placed very “unhandy” with respect to the Mounting bracket and Clips, and some improvements implemented to accommodate mounting issues on other MB’s, it is unfortunately no longer possible to mount the bracket and Clips in the proper orientation. If you are going to use this Mainboard please contact our Support department to obtain a new Clips and mounting bracket. If however you cannot wait and want to try on your own, you are welcome to follow the instructions provided in the attachment to this mail. Should you fail to carry out the alterations, you are of course still welcome to obtain the revised parts from us.

Please make sure that you have understood these issues, and do not hesitate to contact our Customer support, in case you are in doubt of an issue. If you consider these matters carefully, comply with the guidelines provided in the manual and this newsletter, you should not have any problems and obtain very satisfactory results with the Prometeia product.

Please accept our apologies for the problem related to the ABIT TH7 II MB. Orders shipped after today, will have a modified version of the Kit included.

Kind regards

Alteration of P4 mounting kit for use on ABIT TH7 II MainBoard

These instructions are only for users that feel confident they can carry out such alterations, and prefer to do so, in order to get going straight away, rather than resorting to wait for a new Clips and mounting Bracket from Chip-con ApS.

1. The correct orientation of the mounting bracket is with the wider end wall downwards. In this position you will notice that a few components are obstructing the mounting of the Clips in the Bracket.

2. It is necessary to reduce the height from beneath by 1mm of the single Tap holding the Clips in that end, so it provides additional space over the small component located just below it on the MB. Otherwise the Clips is likely to touch that component, which may cause electrical problems. It is recommended to cover the small components with 2 layers of tape for additional insulation and safety.

3. Just next to the centre (and only) Tap in the same end, there is an additional rather tall component on the MB, this is also in the way of the “leg” on the Clips, however since the mounting Clips is not making use of the outer mounting point in that end, this part of the leg on the Clips can just be cut off. Cut as close to the centre mounting point as possible without interfering with that, and at the outside corner of that mounting point. Make sure you make this cut-out in the correct end of the Clips where the brass stand is closest to the “leg” (narrow end of the Clips).

4. To compensate for the 1mm raised Clips position due to this alteration, it is required to add extra spacers in that end under the mounting screw heads of the Cooling Head, to obtain full and proper contact with the heat transfer plate of the P4.

This is the only way you can currently use the System on the ABIT TH7 II, sorry. Do not try to mount the Bracket and Clips and Cooling Head upside down, as this will cause unsatisfactory Cooling performance, and excessive un-evaporated R-134 to return to the Pot inside the Compressor under low to medium load.

We apologise for the extra inconvenience, and hope you will forgive us this blunder.

Kind regards

Seems everybody is waiting for some sort of conversion unit ;)
